Find the volume of a cylinder with a radius of 3 inches and a height of 5 inches.

  1. 141.37
  2. 141
  3. 140
  4. 100

hintHint:

The Volume of cylinder can be found using the formula of the volume of cylinder. The formula of the volume of the cylinder is v space equals space pi r squared h.

The correct answer is: 141.37


    We know that the volume of cylinder is given by v space equals space pi r squared h.
    Where r is the radius of the cylinder and h is the height of the cylinder.
    We are given the radius and height of the cylinder as,
    r equals 3 space i n c h e s and h equals 5i n c h e s
