Find the total surface area of this cylinder.
Give your answer to 1 decimal place.
7 cm
15 cm
Answer:
For the first figure :
Cylinder :
Radius =7cm
height = 15cm
Total Surface Area:
2 \times \pi \times r(h + r)2×π×r(h+r)
= 2×22/7×7 (15+7)
= 22×44
= 968 cm sq.or 9.68m sq.
For the second figure :
Diameter = 24cm (radius= 24/2= 12cm)
•Height = 18 cm
Total Surface area:
2 \times \pi \times r(h + r)2×π×r(h+r)
= 2×22/7×12 (18+12)
= 2×22/7×12 (30)
= 2×22×12×5
= 2640 cm. sq or 26.4 m.sq
The total surface area of this cylinder is 967.1cm²
Surface area of a cylinder.The formula for calculating the total surface area of a cylinder is expressed as:
TSA = 2πr(r+h)
Given the following
radius r = 7cm
Height h =15cm
Substitute
TSA = 2π(7)(7+15)
TSA = 14π(22)
TSA=967.1 cm²
The total surface area of this cylinder is 967.1cm²

Line segment Z E is the angle bisector of AngleYEX and the perpendicular bisector of Line segment G F. Line segment G X is the angle bisector of AngleYGZ and the perpendicular bisector of Line segment E F. Line segment F Y is the angle bisector of AngleZFX and the perpendicular bisector of Line segment E G. Point A is the intersection of Line segment E Z, Line segment G X, and Line segment F Y.
Triangle G E F has angles with different measures. Point A is at the center. Lines are drawn from the points of the triangle to point A. Lines are drawn from point A to the sides of the triangle to form right angles and line segments A X, A Z, and A Y.
Which must be true?
Point A is the center of the circle that passes through points E, F, and G but is not the center of the circle that passes through points X, Y, and Z.
Point A is the center of the circle that passes through points X, Y, and Z but is not the center of the circle that passes through points E, F, and G.
Point A is the center of the circle that passes through points E, F, and G and the center of the circle that passes through points X, Y, and Z.
Point A is not necessarily the center of the circle that passes through points E, F, and G or the center of the circle that passes through points X, Y, and Z.

Beth normally cycles a total distance of 56 miles per week.
She increases her distance by 15% each week for the next three weeks.
How many miles will she cycle in the third week?
(3 marks)
miles
Answer:
She will cycle 85.169 miles in the third week.
(round if needed)
Step-by-step explanation:
56÷100=0.56 (this is 1%)
0.56 x 15 + 56 = 64.4 (you find 15% then add 56 (the original amount) because it's an increase of 15%)
repeat for the other 3 weeks
64.4÷100=0.644
0.644 x 15 + 64.4 = 74.06
74.06÷100=0.7406
0.7406 x 15 + 74.06 = 85.169
Beth will cycle a distance of 85.169 miles in the third week.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If john obtained a score of 57% on his exam, that corresponds to 57 out of 100.
Beth rides her cycle 56 kilometers each week on average.
For the next three weeks, she will increase her distance by 15% each week.
As per the given condition, the required solution would be as
⇒ 56 / 100 = 0.56
⇒ 0.56 × 15 + 56 = 64.4
If we obtain 15%, add 56 (the initial amount) because there is a 15% increase.
Repeat for the remaining three weeks.
⇒ 64.4 / 100 = 0.644
⇒ 0.644 × 15 + 64.4 = 74.06
⇒ 74.06 / 100 = 0.7406
⇒ 0.7406 × 15 + 74.06 = 85.169
Therefore, she will cycle a distance of 85.169 miles in the third week.

Answer:
22.28
Step-by-step explanation:
Since you know the diameter of the semi circle which is 4 because the shape is a parallelogram, you find the circumference of the circle and divide it by two because we only need to know wheat half of the circumference is. When you do this you end up with the answer 6.28. Then you add the lengths of the parallelogram to 6.28, disregarding the circumference of the circle which isn't part of the perimeter. Doing this is 6.28+6+4+6 which equals 22.28 units.

Answer: y=12 x =9
Step-by-step explanation:
In a parallelogram the diagonals bisect each other making them equal.
this means 2y + 6 = 30
we can rearrange this as 30 - 6 = 2y
24 = 2y therefore y = 12
3x - 3 = 24
We can rearrange this as 24 + 3 = 3x
3x = 27
27 / 3 = 9
x = 9

I need help ASAP. Thank you. Special right triangle.
Answer:
JK = 3[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos60° = [tex]\frac{1}{2}[/tex] , then
cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{JK}{JL}[/tex] = [tex]\frac{JK}{6\sqrt{3} }[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2JK = 6[tex]\sqrt{3}[/tex] ( divide both sides by 2 )
JK = 3[tex]\sqrt{3}[/tex]

Mr. Martin’s math test, which is worth 100 points, has 35 problems. Each problem is worth either 5 points or 2 points.
Let x = the number of questions worth 5 points.
Let y = the number of questions worth 2 points.
x + y = 35,
5x + 2y = 100
How many problems of each point value are on the test?
A. 10 problems worth 5 points and 25 problems worth 2 points
B. 15 problems worth 5 points and 20 problems worth 2 points
C. 20 problems worth 5 points and 15 problems worth 2 points
D. 25 problems worth 5 points and 10 problems worth 2 points
Answer:
A
Step-by-step explanation:
a = 10 X 5 = 50, 25 X 2 = 50 = 100
B = 15x5 = 75, 20 x 2 = 40, = 105
C = 20 x 5 = 100, already at 100 (so immediately wrong)
D: 25 x 5 = 125, already larger than 100 (so immediately wrong)
Therefore A is the only correct option, hop i helped you!

Jonathan is making his favorite pasta dish. He serves his mom 1/12 of the pot of pasta and his brother 1/6 of the pot. How much of the pot is left over? PLS HELP I HATE MATH
Answer:
3/4 of the pot left.
Step-by-step explanation:
If the mom eats a 1/12 of the pot and then the brother also eats a 1/6 of the pot, then it is 9/12 left of pasta still. The reason for that is since 1/6 is equivalent to 2/12 so 1/12 plus 2/12 is 3/12, and if u subtract 3/12 from 12/12 it will give you 9/12 which can be simplified to 3/4 left of the pot.
Answer:
3/4 of the pot is left over
Step-by-step explanation:
