The circumference of the base of a cylinder is 88 cm and its height is

1.	The circumference of the base of a cylinder is 88 cm and its height is 15 cm. Find the volume of the cylinder.
Answer» We have, Circumference of base of cylinder = 88 cm Height of cylinder = 15 cm Let ‘r’ be the radius of the cylinder. By using the formula, Circumference of base of cylinder = 2πr So, 2πr = 88 2 × 22/7 × r = 88 r = 88 × 7 / 2 × 22 = 616/44 = 14cm Radius of cylinder = 14 cm ∴ Volume of cylinder = πr²h = 22/7 × 14 × 14 × 15 = 9240 cm³

The circumference of the base of a cylinder is 88 cm and its height is 15 cm. Find the volume of the cylinder.

Answer»

We have,

Circumference of base of cylinder = 88 cm

Height of cylinder = 15 cm

Let ‘r’ be the radius of the cylinder.

By using the formula,

Circumference of base of cylinder = 2πr

So,

2πr = 88

2 × 22/7 × r = 88

r = 88 × 7 / 2 × 22

= 616/44

= 14cm

Radius of cylinder = 14 cm

∴ Volume of cylinder = πr²h

= 22/7 × 14 × 14 × 15

= 9240 cm³
