Question

You are building a teepee so you can be awesome on your next camping

trip. You want it to be 12 feet tall in the center and a 9 foot radius. Using
these dimensions, you find the slant length will be 15 feet.
How big will it be inside? Round to the tenths place.
ft 3

Answer 1

1017.9 ft^3

Explanation:

We know the inside dimension at floor level will be 18 feet across, so that may not be the answer that is being asked for. We also know it will be 12 ft high inside, so that may not be the answer, either. We're not quite sure what "how big" is supposed to mean.

Perhaps the question is trying to ask for the volume of the teepee. That will be given by the formula ...

V = (1/3)πr^2·h

V = (1/3)π(9 ft)^2·(12 ft) = 324π ft^3

V ≈ 1017.9 ft^3

The interior volume will be about 1017.9 cubic feet.
