Question

dia of hollow cylinder 15m and height 12m find the lateral surface of hollow cylinder ​

Answer 1

Given that :-

Diameter = 15m

height = 12m

To Find :-

LSA ( Lateral surface area)

As We Know That,

LSA of cylinder = $2\pi rh$

Radius =$\frac{D}{2}$

           = $\frac{15}{2}$

           = 7.5

Solution :-

=> $2\pi rh$

=> 2 × $\frac{22}{7}$ × 7.5 × 12

=> $565.714 m^2$
