A cylinder has a base area of 154 cm² and a height of 20cm. What is its total surface area, in cm?? Use, 22/7

This is answer A.1188
B.1200
C.1220
D.1224​

Answers

Answer 1

Answer:

Hi there!

We've given with the base area and height. We know the formula for base area

Base area = πr²

154 = 22/7 × r²

154 × 7/22 = r²

49 = r²

√49 = r

7 = r

Now

TSA = 2πr(h + r)

TSA = 2 × 22/7 × 7(7 + 20)

TSA = 44(27)

TSA = 1188 cm²

answer fast meenu sister ​

Answers

Answer:

18

Step-by-step explanation:

3(s-5)/4 -3 = 4s- (s-3)/2

open the bracket

3s-15/4-3 =45-s-3/2

3s-15/1=42-s/2

cross multiply

2(3s-15)=42-s

3s-30=42-s

3s+s=42+30

4s=72

s=18

Answer:

s = -45/13

Step-by-step explanation:

3(s - 5)/4 - 3 = 4s - (s - 3)/2

(3s - 15)/4 - 3 = (8s - s + 3)/2

(3s - 15)/4 - 3 = (8s + 3)/2

3(s - 5)/4 - 3 = 3((8/3)s + 1)/2

3[(s - 5)/4 - 1 ] = 3((8/3)s + 1)/2

(s - 5)/4 - 1 = ((8/3)s + 1)/2

(s - 5)/4 - 4/4 = ((8/3)s + 1)/2

(s - 5 - 4)/4 = ((8/3)s + 1)/2

(s - 9)/4 =((8/3)s + 1)/2

(s - 9) = ((8/3)s + 1)(2)

s - 9 = (16/3)s + 2

s - (16/3)s = 6 + 9

(-13/3)s = 15

s = -45/13

Raw cake batter starts at a thickness of
2 centimeters in a pan but grows at
0.15 centimeters every minute in the oven.
How tall will the cake be after
a certain number of minutes?

Answers

Answer:

y = 0.15x + 2

Step-by-step explanation:

Let's say x represents the number of minutes and y represents the thickness of the cake.

No matter what, the cake will start at a thickness of 2 centimeters. Whatever thickness is added on/subtracted starts at 2 centimeters, so y = 2 + or - something.

Next, the batter grows by 0.15 centimeters every minute. This means that every minute, 0.15 centimeters are added to the thickness of the cake. This can be represented by

0.15 * x

Adding these two together, we get

y = 2 + 0.15 * x

y = 0.15 * x + 2

Find angle A and angle E

Answers

Answer:

m∠A = 50°

m∠E = 50°

Step-by-step explanation:

7x - 17 and 2x + 8 are same side exterior angles. They have a sum of 180°.

7x - 17 + 2x + 8 = 180

9x - 9 = 180

9x = 189

x = 21

∠A and 7x - 17 are supplementary. ∠E and 2x + 8 are vertical angles.

m∠A + 7x - 17 = 180

m∠A + 7(21) - 17 = 180

m∠A + 147 - 17 = 180

m∠A + 130 = 180

m∠A = 50

m∠E = 2x + 8

m∠E = 2(21) + 8

m∠E = 42 + 8

m∠E = 50
