The given question is incomplete. The complete question is:
Estimate the volume of each ball. Use the formula 
where v is the volume and r is the radius. record the volume in table A of your student guide. The radius of the tennis ball is 2.1 cm and the radius of thr golf ball is 2.0 cm. What is the estimated volume of the table tennis ball in 
What is the estimated volume of the golf ball in
Answer: Volume of the tennis ball is 
and Volume of the golf ball is 
Explanation:
We have to find the Volume of tennis ball and golf ball by using the formula
Radius of the tennis ball = 2.1 cm
Radius of the golf ball =2.0 cm.
Putting the value of radius in the formula , we get:
Volume of the tennis ball = 
Volume of the golf ball = 
Volume of the tennis ball is and Volume of the golf ball is
