Question

An Native American tepee is a conical tent. Find the number of cubic feet of air in a teepee 10 ft. in diameter and 12 ft. high. Answer must be in terms of pi

Answer 1

volume of a cone = (1/3) pi r^2 h
where r = radius of the base , h = height

( note r = 1/2 * diameter).

Answer 2

No its r^2 not r

Answer 3

So it would be (1/3)pi (5)^2 * 12
Then I get 1/3 pi 25 * 12 = (1/3) * 300pi
So the answer would be 100pi right?
