Question

the height of a right circular cylinder is 5 cm and the area of its base is 36πcm Find
nurture area of the cylinder.​

Answer 1

Answer:

Given:-

height (h) = 5cm

area of its base (πr²) = 36π cm²

Where, r is the radius of it's base.

πr² = 36π

r² = 36

r = 6cm

Now,we have r = 6cm ,h = 5cm.

and C.s.a of cylinder = 2πrh

2πrh = 2 * π * 6 * 5

= 60π cm²

Hence, the curved surface area of the cylinder = 60π cm²
