tienes que usar la fórmula de: pi por radio al cuadrado
Answer:
[tex]314in^{2}[/tex]
Step-by-step explanation:
Circumference is [tex]2\pi r[/tex]
Find your radius
[tex]2\pi r=62.8\\\pi r=31.4\\[/tex]
Let [tex]\pi =3.14[/tex] for simplicity
r=[tex]\frac{31.4}{3.14}[/tex]=10
Now use the equation for the area of a circle to find the area of the clock face.
Area of a circle is [tex]\pi r^{2}[/tex]
Area of clock face is [tex]\pi (10^{2} )[/tex]
=[tex]100\pi[/tex]
=[tex]314in^{2}[/tex]

Evaluate the expression for the given values of the variables.
(n + 5)2 for n = −7
When n = −7, the expression is equal to...
-4
Step-by-step explanation:
(n + 5)2 for n = -7
= (-7 + 5)2
= (-2)2
= -4
Another way :
(n + 5)2
= 2n + 10
= 2(-7) + 10
= -14 + 10
= -4

50 = -1/3b + 20
what is b?
To find b, start by subtracting 20 from both sides:
50 = -1/3b + 20
-20 -20
30 = -1/3b
Now isolate b by dividing both sides by -1/3:
30/(-1/3) = (-1/3b)/(-1/3)
-90 = b
b is 90!
hope this helps !!

Step-by-step explanation:
The coordinates of point J are (-7, 2), and the midpoint of JK is at L (3, 5). What are the coordinates of point K?
The required coordinate of the point K is (13, 8).
Given that,
The coordinates of point J are (-7, 2), and the midpoint of JK is at L (3, 5), the coordinates of point K is to be determined.
Coordinate, is represented as the values on x-axis and y-axis of the graph.
here,
The coordinate of the midpoint (x, y) is given as,
x = (x₁ + x₂)/2 ; y = (y₁ + y₂)/2
Substitute the value in the above equation,
3 = (-7 + x₂)/2 ; 5 = (2 + y₂)/2
x₂ = 13 ; y₂ = 8
Thus, the required coordinate of point K is (13, 8).

Please help. I can't figure it out.
Answer:
see explanation
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides )
Here n = 5 , then
sum = 180° × 3 = 540°
Sum the given angles and equate to 540
2b - 90 + 90 + b + 45 + b + [tex]\frac{3}{2}[/tex] b = 540, collect like terms
4b + 1.5b + 45 = 540 ( subtract 45 from both sides )
5.5b = 495 ( divide both sides by 5.5 )
b = 90
then
2b - 90 = 2(90) - 90 = 180 - 90 = 90
b + 45 = 90 + 45 = 135
[tex]\frac{3}{2}[/tex] b = 1.5b = 1.5 × 90 = 135
The angles from least to greatest are
90° , 90° , 90° , 135° and 135°

Step-by-step explanation:
The points H, I, J and K all lie on the same line segment, in that order, such that the
ratio of HI:IJ: JK is equal to 3: 3:4. If HK - 40, find IJ.
Answer:
IJ = 12
Step-by-step explanation:
sum the parts of the ratios, 3 + 3 + 4 = 10 parts
Divide HK by 10 to find the value of one part of the ratio.
40 ÷ 10 = 4 ← value of 1 part of ratio , then
IJ = 3 parts = 3 × 4 = 12

Help!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
x = 32
Step-by-step explanation:
The angle above 72° is 108° because they are supplementary angles, meaning they add up to 180°. Then we can set the equation 108° = (3x + 12)° because they are alternate interior angles, meaning that they are the same. So then we just solve for x.
108 = (3x + 12)
108 - 12 = 3x
96 = 3x
96 / 3 = x
32 = x

you are driving to a friends house at 35 miles per hour and the friend lives 21 miles away. how long to get to the house
Answer:
35miles/1 hr=21miles/x hr
= x hr* 35miles/1 hr= 21 miles
= x = 21/35 =0.6 hr
So, traveling at 35mph it will take 0.6 hours to travel 21 miles.
If you want time in mins then keep going:
=> 60 mins = 1 hour, 0.6 hours = x mins
60mins/1 hr = x mins/ 0.6 hr
0.6 * 60 mins = 36 mins.
:. It takes 0.6 hrs or 36 mins to drive 21 miles at a constant speed of 35mph
