Question

A sphere has a diameter of 14 units. What is the volume of the sphere in cubic units? If a cylinder has the same radius as the sphere and a height

of 14 units, what is the volume of the cylinder? Use 3.14 for pie

A). The volume of the sphere is about 1,077.02 cubic units, and the volume of the cylinder is about 718.01 cubic units.

B). The volume of the sphere is about 1,436.03 cubic units, and the volume of the cylinder is about 2.154.04 cubic units.

C). The volume of the sphere is about 1,436.03 cubic units, and the volume of the cylinder is about 957.35 cubic units.

D). The volume of the sphere is about 1,077.02 cubic units, and the volume of the cylinder is about 1,615.53 cubic units.

Answer 1

B

Explanation:

r = 14/2 = 7units

Answer 2

B

Explanation:

r = 14/2 = 7units

`Volume of sphere=(4)/(3)*\pi*r^(3)\\\\=(4)/(3)*3.14*7*7*7\\\\=1436.03cubic units\\\\Volume of cylinder=\pi*r^(2)*h\\\\=3.14*7*7*14\\\\=2154.04 cubic units`
