Question

Find the height of a cylinder when the surface area is 1004.80 cm squared and the radius is 10 cm.

Answer 1

Explanation:

`volume =\pi {r}^(2)h`

`area = \pi {r}^(2)`

CALCULATION

remember

`\pi = 22 / 7`

So, we will just place the area and equate it to the unknown volume including the height

1004.80 = 22/7 × 10× 10 × h

1004.80 = 314.26h

h = 3.197
