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 $$V = \pi r^2 h$$

Plugging stuff in, we have $$V = \pi * (15/2)^2* 8$$

Solving gives us $$V = 450 \pi$$

or V = 450pi units^2

//edit

I should clarify that r = d/2. That's why I used 15/2.
