Question

Curved surface area of a cylinder is 880 m², whose height is 10 m. Find volume of cylinder. (π = 22/7)

Answer 1

Let r and h be the radius and height of the solid right circular cylinder respectively.

Let S be the total surface area of the solid right circular cylinder.

Given that r = 10cm and S = 880 m²

2 x 22/7 x r x10 = 880

r = \(\frac{880\ \times\ 7}{2\times22\times10}\) m

r = 14 m

Volume of cylinder = πr²h

= 22/7 x 14 x 14 x 10 m³

= 6160 m³
