1) The formula for volume of a sphere is:


(4)/(3) \pi r^3

r is the radius

To find the volume, you would just substitute the radius into that formula to get the volume

2) The formula for volume of a cone is:


(1)/(3) \pi r^2h

Again, just substitute the radius in and solve.

3) The radius is half of the diameter so you would just divide the diameter by 2.

Hope This Helps You!

Good Luck (:

Have A Great Day ^-^
