explain please

anonymous · Answer

I plugged it into the formula for a cone, which is (pi)(r)^2(h/3) and solved. The height is 24, and I divided 72 by 2 and got 36 to plug into the radius.
(Diameter is 2 times radius)

anonymous · Answer

don't you do something like this diameter/n2 the diameter is 72 so plug that in and divide and that wll be your radius?

The formula for a right circular cone is πr^2(h/3)

anonymous · Answer

Pi(r)^2(h/3)

Plug the values into this calculator, but plug 36 into the radius, not 72 b/c that is the diameter. https://www.google.com/webhp?sourceid=chrome-instant&rlz=1C1GGGE_enUS416&ion=1&espv=2&ie=UTF-8#q=formula+for+a+cone
