Question 659791

{{{V=(4/3)pi*r^3}}} and 

{{{S=4*pi*r^2}}}

If {{{S=100*pi}}},

find {{{V}}}..........{{{pi=3.14}}}, not {{{3.24}}}

______________________

If {{{S=100*pi}}}...=> {{{4r^2=100}}}..=> {{{r^2=100/4}}}.=> {{{r^2=25}}}.=> {{{r=5}}}, plug it in {{{V}}}


{{{V=(4/3)pi*5^3}}}

{{{V=(4/3)3.14*125}}}

{{{V=(4/3)392.5}}}

{{{V=(1.33)392.5}}}

{{{V=522.025}}}
