    cylinder volume formula

    v = (π * r²) * h

    Step-by-step explanation:

    To calculate the volume of a cylinder we have to multiply the height by the area of the circle that is the base

    The area of a circle is calculated with this formula (a = π * r²)

    Let's do an example where the radius is 5.5ft and the height is 13ft to see how to calculate the volume

    To calculate the volume of a cylinder we have to use the following formula:

    v = volume

    h = height = 13ft

    π = 3.14

    r = radius = 5.5ft

    v = (π * r²) * h

    we replace the unknowns with the values we know

    v = (3.14 * (5.5ft) ²) * 13ft

    v = (3.14 * 30.25ft²) * 13ft

    v = 94.985ft² * 13ft

    v = 1234.805ft³

    The volume of the cylinder is 1234.805ft³

    Calculate the area of the base (which is a circle) by using the equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder to find the volume.
