Final answer:
To find the volume of the tennis ball, substitute the radius value into the formula V = (4/3)×πr3.
Step-by-step explanation:
The formula for the volume of a sphere is V = (4/3)×πr3. To find the volume of the tennis ball, we need to substitute the value of the radius which is equal to half of the diameter.
So, the radius would be 34 mm. Plugging this value into the formula gives us V = (4/3)×π(34)3.
Evaluating this expression will give us the volume of the tennis ball.
