The volume of cylinder is i408 cmheight is 7 cm find the curved surface area!

Answer»

Given,Volume of cylinder V = 1408 cm^3Height of cylinder h = 7 cm

Let radius of cylinder = r

Volume of cylinder= pi*r^2*h

1408 = 22/7*r^2*7r^2 = 1408/22 = 64r = 8

Curved surface area of Cylinder = 2*pi*r*h= 2*22/7*8*7= 44*8 = 352 cm^2
