Find the diameter of the ball::
pi*d = 22
diameter = 22/pi inches
-----------------------------
(a) What is the volume of the ball in cubic inches?
V = (4/3)pi*r^3 = (4/3)pi*(11/pi)^3 = (1774.67)/pi^2 in^3
----------------------------------------------------------
(b) What is the smallest possible volume for the box? in3
V = s^3 = (22/pi)^3 = 10648/pi^3 in^3
--------------------------------------------
(c) What percent of the space in the box is occupied by the ball?
[(4/3)pi*(11/pi)^3 / (22/pi)^3 = [(4/3)*11^3/p^2]/(22/pi)^3)
= [(4/3)*11^3*pi/22^3] = 52.36%
