The formula for determining the volume of a cylinder is expressed as

Volume = pi * radius^2 * height

Radius, r = diameter/2

Given that diameter = 4, r = 4/2 = 2 cm

height = 3.6 cm

pi = constant = 3.14

Volume = 3.14 * 2^2 * 3.6

Volume = 45.216 cm^3

Rounding up to the nearest whole number,

Volume = 45 cm^3

The correct option is number 3
