Question 762932

the volume is {{{V=(1/3)pi*r^2*h}}}


if the volume is {{{300cm^3}}} and the height is {{{h=20cm}}}, then


{{{300cm^3=(1/3)3.14*r^2*20cm}}}.....solve for {{{r}}}


{{{300cm^3=20.933cm*r^2}}}


{{{300cm^3/20.933cm=r^2}}}


{{{14.33cm^2=r^2}}}


{{{sqrt(14.33cm^2)=r}}}


{{{3.79cm=r}}}
