Question

The formula for the volume of a cone is V=1/3(pi)r^2(h). Find the radius, to the nearest hundredth, of a cone with a height of 5 in. and a volume of 20 in^3. How do you do this? Thank you

Answer 1

V = 1/3(pi)r^2(h)

V = volume, h = height, r = radius, so...

20 = (1/3)(pi)(r^2)(5)

solve for r

Answer 2

Oh ok thank you I will try it now
