Question

The base area of a right circular cylinder is 16π cm² .Its height is 5cm. Find the curved surface area? *​

Answer 1

Here, radius is 4.

So, Curved Surface Area = 2πrh

Therefore, Curved Surface Area = 880/7 = 125.71....

Hope it helps.

Answer 2

Step-by-step explanation:

Answer

πr² =616

r²= 616 × 7 / 22

r² = 28×7

r = square root of 196

r=14

C.S.A=2πrh

2× 22/7 × 14× 2.5

=220cm²
