Answer:
1017.9 ft^3
Step-by-step 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.
Step-by-step explanation:
The equation will form a circle because it in the form of

First, let set the equation equal.

Here the center will be (7,-5), and the radius of 5. The boundary line will be dashed
Since this is in the inequalities, we must find the solution set.
Plug in 0,0 for x and y and see if it's true.



This is a true so we shade the region that includes 0,0
Since 0,0 has a greater distance from the center of the circle, 0,0 is outside of the circle, so our solution set will
be outside of circle.
