If r=4cm and h = 4cm, what is the volume of the cone

volume cone = 1/3 pi r^2 h

volume cylinder = pi r^2 h

Step-by-step explanation:

1. Volume = 1/3 x pi x r^2 x h = 12 X pi

2. 100 pi = 1/3 x pi x r^2 x 12

r^2 = 25

r = 5 cm

3. volume = pi x 16 X 5 = 80 pi cubic meters

4. 400 pi = pi x r^2 X 4

r^2 = 100

r = 10 yards
