Question

Qs4: The height of cylinder is 40cm
and diameter of the base is 7cm. Find
the curved surface area of the cylinder​

Answer 1

Answer:

957cm²

Step-by-step explanation:

Given:

The height of cylinder is 40cm

The height of cylinder is 40cmand diameter of the base is 7cm.

To find:

the curved surface area of the cylinder.

Solution:

We know that surface area of cylinder=2πr(r+h)

Given: d = 7cm and h = 40cm.

Total surface area =2πr(r+h)

= 2π3.5(3.5+40)

= 396.13

.°. T.S.A = 957cm²
