Question

The circumference of the base of a right circular cylinder is 88 cm. If the height of the
cylinder is 10 cm. Calculate the volume of the cylinder.​

Answer 1

circumference =2πr

2 π r = 88

2 × 22 / 7 × r = 88

r = ( 88 × 7 ) / ( 22 × 2 )

r = 2 × 7

r = 14

volume = π r² h

= 22 / 7 × ( 14 )² × 10

= 22 / 7 × 196 × 10

= 22/7 × 1960

6160= cm³
