Question

The volume of a right circular cylinder is represented by V = πr ²h
where r is the radius of the base (in feet). What is the radius of a right
circular cylinder when the volume is 144 π cubic feet and the height
is 9 feet?

    The radius is 4 feet.

    Plug in what you know to the formula you have:

    144π = π(r)^2(9)
    Divide both sides by pi to get rid of that.
    144 = 9(r)^2
    Divide both sides by 9
    16 = r^2
    r = square root of 16 = 4
