Stacy hits the jackpot one day at the gumball machine. she puts in a quarter and gets 4 gumballs rather than 1. the radius of each gumball is 6 mm. what is the total volume of all 4 gumballs?

Use the formula for the total volume of a sphere:



V represents your volume, and r represents the radius.

Plug your radius into the formula.











The total volume of a single gumball will be 288π cubic millimeters.

Because you have 4 gumballs, multiply the total volume of a gumball by 4 to find the total volume for all 4 gumballs.



In terms of π, the total volume of the 4 gumballs is 1152π cubic millimeters.

Assuming π = 3.14, multiply 1152 and 3.14 together.



The total volume of the 4 gumballs, simplified, is 3617.28 cubic millimeters.

J= r + 9 because since jessica rode 9 more miles than roger, you add 9 miles to rogers mileage.
