Question

The area of the base of a right circular cylinder is 15400 Cm^2 and its volume is 92400 cm^3 . Find the area of the curved surface.

Answer 1

Given,

Area of base = 15400
So, π*r^2 = 15400 eq1

r is 70

Also, π* r^2 * h = 92400 eq2

Dividing eq2 by eq1,
we get

h = 6

So, CSA = 2 * π * r * h

= 22 * 84
= 11 * 168

= 1848 cm^2
