Find the volume of the following pyramids and cones. 50 POINTS Please answer all for points.

1. V = 400 cm^3

2. V=7.26pi ~ 22.807 cm^3

3. V=(200/3)pi ~ 209.439 m^3

4. V= 72 m^3

Step-by-step explanation:

1. V=(l*w*h)/3

V=(10*10*12)/3

V= 400 cm^3

2. V=pi*r^2*(h/3)

V=pi * (2.2)^2*(4.5/3)

V=7.26pi ~ 22.807 cm^3

3. V=pi*r^2*(h/3)

V=pi * 5^2 * (8/3)

V=(200/3)pi ~ 209.439 m^3

4. V=(l*w*h)/3

V=(4*6*9)/3

V= 72 m^3
