Question

A cone has a radius of 11 inches and a height of 4.5 inches what is the volume of the cone use 3.14 for pie round to the nearest 10th

Answer 1

To solve this, you must know that the volume of a cone is
1/3* PI * r^2 * h = V
(r^2 = r squared)

Now we just plug in! Because you specified 3.14 for pi, replace!

=> 1/3 * 3.14 * (11)^2 * 4.5
=> 569.91
Nearest tenth
=> 569.9 inches cubed.
