Question

A sphere has a radius of 5.3 feet.

What is the volume of the sphere to the nearest tenth?

Use 3.14 for pi

Answer 1

Remember the equation for the volume of a sphere is:
`V = (4)/(3) \pi r^(3)`
where V=volume and r =radius

Since you know the radius is 5.3 ft, plug that into the equation for volume of a sphere:

`V = (4)/(3) \pi r^(3)\\ V = (4)/(3) (3.14) (5.3)^(3)\\ V= 623.3 ft^(3)`

The volume of the sphere is: 623.3
`ft^(3)`

Answer 2

V = (4/3)π*r^3
.. = (4/3)*3.14*(5.3 ft)^3
.. = 623.3 ft^3
