Now for the problem

Answer 2

Okay. I know the height is 9 yd

Answer 3

4/2 = 2

Answer 4

So, I think 2 would replace r?

Answer 5

height = 9 yards
radius = 4 yards
Surface area =
2*PI*4*4 PLUS
2*PI*4 * 9

Answer 6

Surface Area =
PI * 32 PLUS PI * 72

Answer 7

Do I multiply with the equation?

Answer 8

Pi

Answer 9

Total Area = 104 * PI
