The formula for finding the volume of a cone is \large V=\frac{1}{3}\pi r^2h. The volume of a cone is 300 cm^3 and the height is approximately 11.5 cm, what is the approximate radius of the cone?
a
9 cm
b
3 cm
c
29 cm
d
5 cm

The robot's answer is wrong as usual
V = (1/3) π r^2 h
using our given:
300 = (1/3)π r^2 (11.5)
78.26087 = π r^2
r^2 = 24.9112..
r = 4.991... or appr 5
V = (1/3) π r^2 h
using our given:
300 = (1/3)π r^2 (11.5)
78.26087 = π r^2
r^2 = 24.9112..
r = 4.991... or appr 5
