Question

Consider the diagram shown. The sphere and cylinder have the same diameter. The height of the

cylinder is equal to the diameter of the sphere.
Find the approximate volume of the sphere by using 3.14 for 7. Round to the nearest tenth
of a cubic unit.
8.4
8.4

Answer 1

310.2 cubic units

Explanation:

since we know the diameter of the sphere (8.4), the radius is
`8.4/2 = 4.2`

The volume of a sphere is
`(4)/(3)\pi r^3`

Plugging in 3.14 as
`\pi` and 4.2 as r, we get 310.2
