A cylinder has a volume of 320 cu in. and a height of 5". Find the radius of the cylinder. 10 in. 8 in. √8 in.
Reptile [31]
The correct question is
<span>A cylinder has a volume of 320 pi in</span>³<span>. and a height of 5". Find the radius of the cylinder</span>
we know that

[volume of a cylinder]=pi*r²*h----> r²=volume/(pi*h)
r=√[volume/(pi*h)]
volume=320*pi in³
h=5 in
so
r=√[320*pi/(pi*5)]--------> r=8 in

the answer is 
8 in
