Question

There are many cones with a height of 12 inches. Let r represent the radius and V represent the volume of these cones.

a. Write an equation that expresses the relationship between V and r. Use 3.14 as an approximation for π.

Answer 1

The short answer is just
V=3.14 r squared and 12/3

Answer 2

V= 3.14 r^2 12/3

Hope this equation helps!
