Question

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

Answer 1

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.

Answer 2

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

Answer 3

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

Answer 4

12,000 ?

Answer 5

37680
is this in the options

Answer 6

@Shawna23 But you need to multiply 12000 by pi to get the answer.

Answer 7

Answer 8
