How do you find the volume of a right cylinder with a diameter of 15 and a height of 8?
Looking at Google, the formula for the volume of a cylinder is V=πr2h
Plugging stuff in, we have V=π∗(15/2)2∗8
Solving gives us V=450π
or V = 450pi units^2
//edit
I should clarify that r = d/2. That's why I used 15/2.
