<PRE><B>Question 358854</B>
a beach ball holds 800 cubic inches of air. another beach ball has a radius that is half that of the larger ball. how much air does the smaller ball hold?

------
Radius of 800 cubic in ball = ?
(4/3)pir^3 = 800
r^3 = 190.99 in
r = 5.759 in
----
Vol. of smaller ball
V = (4/3)pi(5.759/2)^3
---
V = 100 cu inches
