Question

circumference of the base of a cylinder is 88 cm and its height is 15 cm find the volume of the cylinder

Answer 1

Height of cylinder = 15 cm

Circumference of Base of cylinder = 88 cm

=> 2 pi r = 88

=> 2 × 22× r / 7 = 88

=> r = 88 × 7 / 44

=> r = 2 × 7

=> r = 14 cm

Radius of Base of cylinder = 14 cm

Now,

Volume = pi r^2 h

= 22 /7 × 14 × 14 × 15

= 22 × 2 × 14 × 15

= 44 × 210

= 9240 cm^3

Answer 2

Circumference=2πr
88= 2πr
r= 88×7/22
r=14cm
Vol of cylinder=πr ×r×h
=22/7×14×14×15
=9240cm square
