How to calculate the volume of a cylinder

The formula for calculating the volume of a cylinder is given as:

V = πr²h

Given

radius = 4.5cm

Height = 7.5cm

Substitute

V = πr²h

V = 3.14 * 4.5² * 7.5
V = 476.8875 cubic cm

Determine the number of coasters

Number of coasters = 476.8875/95.43
Number of coasters = 5

Hence the approximate number of coasters that you need to reach a height of 7.5 cm is 5 coasters
