Question

Find the diameter of a cylinder whose height is 5cm and numerical value of volume is equal to numerical volume of curved surface area ? Solution Fast Reply Me​

Answer 1

Volume V = π * r ^ 2 * h

Curved Surface Area A = 2 * π * r * h

We know that V = A

Therefore ,

π * r ^ 2 * h = 2 * π * r * h

Therefore r ^ 2 = 2 * r

or

r = 2

Thus d=r×2=2×2=4 cm
