Question

The circumference of the base of a right circular cylinder is 314 cm. Find its volume if its height is 21 cm.

Answer 1

this is the answer may be this can help u

Answer 2

Volume of the cylinder is 164670.165 cm³

Given data :

Base circumference = 314 cm

Height = 21 cm

Let the radius = r cm

So,

2πr = 314

2× 22/7 × r = 314

r = 314 × 7/44

r = 49.95 cm

Volume = π × (49.95)² × 21 = 22/7 × 49.95 × 49.95 × 21 = 164670.165 cm³ (answer)
