Question

The circumference of the base of a cylinder is 264cm and its height is 24cm. Find the radius of the cylinder.

Answer 1

Given:-

• Circumference of base = 264cm

• Height=24cm

TO Find:-

• radius of cylinder.

Explaination:-

To find volume,

first we have to find the radius with the help of circumference.

Circumference=2πr

264= 2× $\frac{22}{7}$× r

$\frac{264}{2}$ = $\frac{22}{7}$ × r

132 × 7 = 22r

924 = 22r

r = $\frac{924}{22}$

r = 42cm

Volume of cylinder = πr²h

volume = $\frac{22}{7}$× 42 × 42 × 24

=22 × 6 × 42 × 24

=132 × 1008

Volume = 133056cm³

Answer 2

Step-by-step explanation:

Circumference of base=264cm

Height=24cm

Volume=?

To find volume,first we have to find the radius with the help of circumference.

Circumference=2πr

264=2×22/7×r

264/2=22/7×r

132×7=22r

924=22r

r=924/22

r=42cm

Volume of cylinder=πr²h

volume=22/7×42×42×24

=22×6×42×24

=132×1008

{\boxed{\blue{Volume=133056cm^3}}}

Volume=133056cm 3 square
