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. 100 cu. ft. 300 cu. ft. 400 cu. ft.

Answer 1

For this case what you should know is that by definition the volume of the cone is given by:
 V = ((pi) * (r ^ 2) * (h)) / (3)
 Remembering that:
 r = d / 2
 Substituting the values:
 V = ((pi) * ((d / 2) ^ 2) * (h)) / (3)
 V = ((pi) * (((10) / 2) ^ 2) * (12)) / (3)
 V = 314.16 ft ^ 3
 Answer:
 V = 314.16 ft ^ 3
 The nearest option is:
 300 cu. ft
