Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

Opps, sorry I meant 4. But thanks!
