volume of a cylinder = $\large \pi r^2 h$   r = radius,    h = height

I know that. I need help with the height part. Is it 5*3 Or 5^3

jdoe0001 · Answer

well   the diameter is 8... and the radius is half of the diameter  thus  $\bf radius=\frac{\cancel{ 8 }}{\cancel{ 2 }}\to 4\qquad {\color{brown}{ 3}}\times 4\to 12=h$

Opps, sorry I meant 4. But thanks!
