Question

A cone has a diameter of 18 units and height of 8 units. What is its volume? in units

Answer 1

Answer: 678.58

Explanation:

The equation is pi r² h/3 (all multiplied)

diameter is 18 so in order to find out the radius we have to divided by 2 since 2r = d. 18/2=9. pi x 9 x 8/3 = about 678.58
