Question

The volume of a sphere is 5,572.45 ft To the nearest foot what is the radius of the​ sphere? Use 3.14 for .

Answer 1

Answer:
`11\ ft`

Explanation:

Given

The volume of a sphere is
`5572.45\ ft^3`

The volume of sphere with radius r is given by

`\Rightarrow (4\pi r^3)/(3)`

Insert the values

`\Rightarrow V=(4\pi )/(3)* r^3\\\\\Rightarrow 5572.45=(4\pi )/(3)* r^3\\\\\Rightarrow r^3=(5572.45* 3)/(4\pi )\\\\\Rightarrow r^3=1330.992\\\\\Rightarrow r=10.97\approx 11\ ft`

Therefore, the radius is
`11\ ft`
