Work out the volume of this sphere. Give your answer to 1 decimal place.
Spheres
Vol = ar
19 cm

The volume is;

3951.8 cm^3

Step-by-step explanation:

As we can see, the sphere diameter is 19 cm

Radius is half of this which is 19/2 = 9.5 cm

Putting this in the area , we have

4/3 * 3.142 * 9.5^3 = 3951.8
