Aguest house is in the shape of a cone. the house is 7.5 feet high, 22 feet long. find the volume of air that occupies the house, assuming it is empty.

The formula for volume of a cone is V=(1/3)*h*π*(r^2)
our height is 7.5 feet, and since the length of the base of the cone (diameter) is 22 feet long, the radius is 11 feet long.
(1/3)*7.5*π*(11^2)=302.5*π=950.3
so the volume of the house is about 950 feet cubed.

3m - 9 = 9 + 3m
-3m             -3m
0m - 9 = 9
       +9  +9
     0m = 18
       0      0
       m = 0
B. no solution
