$$V = \frac{ 4 }{ 3 }\pi r^2$$

calculusxy · Answer

Our diameter is 20 inches, and radius is always half of diameter. Thus, the radius is 20/2 which equals .... ?

anonymous · Answer

r=10

calculusxy · Answer

yes now plug those info into the formula given

anonymous · Answer

so V=4 over 3 pi10^2??

calculusxy · Answer

yes 
$$\frac{ 4 }{ 3 }\pi (10)^2$$
$$\frac{ 4 }{ 3 }(\frac{ 22 }{ 7 })10^2$$
