## anonymous 4 years ago 1) What is the volume, in cubic centimeters, of a cylinder that has a height of 15 cm and a diameter of 12 cm?

1. Mertsj

The volume is the area of the base times the height. The base of a cylinder is a circle.

explain simply please T-T

3. Mertsj

$V=\pi r^2h$

4. Mertsj

$V=\pi (6)^2(15)$

6. Mertsj

$V=540\pi$

i did that but had a ridculouys number of 1696.5

"simply" is a rather subjective term

-_- im not in college -_-

Well that is correct is you multiply by 3.14 instead of leaving it in terms of pi.

respect the drawing the circle's area = the radius (half of the diameter) which is 6, squared, which is 36 multiplied by pi, then take 36pi and multiply it by the height to get 540 times 3.14

oh o_o i thought it was wrong thanks! :D
