A CD tower is shaped like a cylinder and holds CDs with a diameter of 4.75 inches. If the CD tower is 12 inches tall, what is its volume in cubic inches? Use 3.14 for pi. Round your answer to the nearest hundredth.
212.54 cubic inches
231.56 cubic inches
850.16 cubic inches
867.34 cubic inches
can anyone help explain this to me ?
the formula is V=πr^2h

Best ResponseYou've already chosen the best response.0Well you know the height= 12in You don't know the radius but you can find it since the diameter is given radius=1/2 diameter diameter=4.75 r=1/2(4.75in) r=? h=12in V=πr^2h

Best ResponseYou've already chosen the best response.0212.54 the formula is the area of your base times your height. So it would be 4.75 divided by 2 in order to get your radius, the you would square it and multiply it by 3.14 and then multiply it by 12:)

Best ResponseYou've already chosen the best response.0Btw @deeezzzz the volume of the cylinder is 3.14 x r( squared) x height. You dont multiply the height by 2
