Estimate the volume of each ball. Use the formula where V is the volume and r is the radius. Record the volumes in Table A of your Student Guide.
What is the estimated volume of the table tennis ball?
cm3
What is the estimated volume of the golf ball?
cm3

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

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

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
