An average clementine is shaped like a sphere and has a diameter of 3.5 inches. what is the volume of the fruit? use 3.14 for pi. round your answer to the nearest hundredth. -20.45 cubic inches - 21.34 cubic inches - 22.44 cubic inches - 23.78 cubic inches

The formula for the volume of a sphere is 
We know the diameter, but we can easily convert this into the radius by dividing it by 2, since the diameter is twice as long as the radius.
3.5/2 = 1.75
Now we can find the volume.

So, the average volume of a clementine is 22.46 cubic inches
 The closest option you have is 22.44 so if you round it that should be your answer.
