Question

The circumference of the base of a cylinder is 88cm and its height is 30cm. Find the volume of the cylinder

Answer 1

2πr = 88
then r = 88/2π = in 14cm
volume = πr^2h = 18480cm^3

Answer 2

base of a cylinder ( diameter )= 88cm
radius of the cylinder =88/2 = 44cm
height of the cylinder = 30cm

Therefore, Volume of the cylinder= πr²h
= 22/7× (44)² × 30
= 22/7 × 1936 × 30
= 22 × 276.57142857 × 30
= 182537.14286 cm³ approx
