Question 159743
A spherical balloon is inflated so that its diameter is 40 ft. Find the surface area in the balloons covering and the volume of the gas. Show solutions and
 formulas.
:
Two formulas needed here
Vol = {{{(4/3)pi*r^3}}}
and
Surface Area = {{{4*pi*r^2}}}
:
radius = 40/2 = 20 ft
:
S.A = {{{4*pi*20^2}}}
S.A = 5026.548 sq ft
and
V = {{{(4/3)pi*20^3}}}
V = 33,510.32 cu ft
