IM GIVING 80 POINTS!!A silo consists of a cone stacked on top of a cylinder, where the radii of the cone and the cylinder are equal. The diameter of the cylindrical base of the silo is 12 ft and the height of the cylinder is 10 ft, while the height of the cone is 8 ft. Calculate the surface area of the silo. Leave your answer in terms of π. 480π sq. ft. 276π sq. ft. 216π sq. ft. 204π sq. ft.

^2 means "squared"

pi = 3.1415926

Volume of a cylinder = height x pi x (radius^2)

volume of a cone = (1/3) x height x pi x (radius^2)

So, (1/3) x 10 x π x (6^2)

This should be the answer : 376.991118
