1.) find the volume of this cylinder. diameter 8cm and height=7cm. round to the nearest hundredth.

2.) find the volume of the cone. diameter=4m and height= 6m. round to the nearest hundredth.

3.) find the volume of the sphere. Radius=5m. round the the nearest hundredth.

4.) find the volume of the sphere. Diameter=13m. round to the nearest hundredth.

just plug your numbers into the standard formulas.
sphere: 4/3 πr^3
cylinder: πr^2 h
cone: 1/3 πr^2 h
where r is the radius (half the diameter)
come back if you get stuck, and show what happened.
