A rate is a comparison that provides information such as dollars per hour, feet per second, miles per hour, and dollars per quart, for example. The word “per” usually indicates you are dealing with a rate.
You could answer this by rearranging the equation to make r the subject:
539 = π ×
× h
÷ πh
539 ÷ (π × h) =
√
√(539/π × h) = r

The volume of a cone is given by the formula
, where <em>r</em> is the radius and <em>h</em> is the height. The horizontal dotted line from the center of the base circle to the outside edge would be the radius, so that would be 12 cm. The vertical dotted line from the center of the base to the point of the cone would be the height, so that would be 8 cm. We substitute these values into our formula:
Substituting 3.14 for pi we have:
