The formula for volume of a cone is V = PI x r^2 x h/3 where r is the radius and h is the height.
Volume of cone = 3.14 x 7^2 x 12/3
Volume of cone = 3.14 x 49 x 4
Volume of cone = 615.44 cubic inches.
The formula for volume of half a sphere is : 1/2 x (4/3 x PI x r^3)
Volume for half sphere = 1/2 x (4/3 x 3.14 x 7^3)
= 1/2 x 4/3 x 3.14 x 343
= 718.01 cubic inches.
Total volume = 615.44 + 718.01 = 1333.45 cubic inches.
Rounded to the nearest tenth = 1,333.5 cubic inches.
