1.	Q6. Find the diameter of a cylinder whose height is 5cm and numerical value of volume equal to numerical valeeof curved surface area.
Answer» 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 = 2Thus d=r×2=2×2=4 cm

Q6. Find the diameter of a cylinder whose height is 5cm and numerical value of volume equal to numerical valeeof curved surface area.

Answer»

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

r = 2Thus d=r×2=2×2=4 cm
