Final answer:
The question requires calculating the volume of a teepee modeled as a cone. Using the formula V = (1/3)\u03c0r^2h with the given height and radius (half the diameter), the volume is found to be 471.2 ft cubed. The correct answer is D.471.2 ft cube.
Step-by-step explanation:
The question asks us to calculate the volume of a teepee, which can be modeled as a cone, given its height and diameter. The formula for the volume of a cone is V = (1/3)\u03c0r2h, where r is the radius of the base and h is the height of the cone. With a diameter of 15 ft, the radius is half of that, which is 7.5 ft. The height of the teepee is given as 8 ft. Plugging these values into the formula, we get:
V = (1/3)\u03c0(7.5 ft)2(8 ft)
Now, calculate the volume:
V = (1/3)\u03c0(56.25 ft2)(8 ft)
V = (1/3)(176.625 ft3)
V = 471.2 ft3
The correct answer is D.471.2 ft cube.
