See a solution process below:

A beach ball is a sphere. The formula for the volume of a sphere is:

#V_s = 4/3pir^3#

Substituting #3.14# for #pi# and #18" in"# for #r# and calculating #V# gives:

#V_s = 4/3 xx (3.14) xx (18" in")^3#

#V_s = 12.56/3 xx 5832" in"^3#

#V_s = (12.56 xx 5832)/3" in"^3#

#V_s = (12.56 xx 1944)" in"^3#

#V_s = 24416.64" in"^3#
