Question

Some candles are in the shape of a right circular cylinder. For one such candle, the radius is 9 cm and the height is 26.5 cm. Find the volume of the candle.

Round your answer to the nearest whole number. Do not type the units in the space below.


(Be sure to use the pi button on your calculator to do the calculation.)

Answer 1

Explanation:

the volume of such a regular cylinder is (as for any regular object) :

base area × height

and for a cylinder the base area is a circle, and its area is

pi×r²

so, combined, the volume of our cylinder is

pi×r²×height = pi×9²×26.5 = pi×81×26.5 =

= 6,743.428631... cm³

≈ 6,743 cm³
