A right cylinder has a diameter of 40 mm and a height of 30 mm What is the volume of the cylinder?

Question

kropot72 · Answer

The formula for the volume V is
$$V=\pi r ^{2}h$$
In this case the radius r = 40/2 and h = 30. So just plug in these values and calculate.

I get 150,796mm3 and that is not a answer I can choose

kropot72 · Answer

Plugging into the formula gives:
$$V=\pi \times 400\times 30=?$$
Can you calculate the volume now?
