Question

If the volume of the crystal ball is about 113.14 cm3, the radius of the ball is approximately

Answer 1

B and B for plato

Explanation:

Answer 2

r ≅ 3.00

Explanation:

First we need to get the formula for finding the volume of sphere. The formula is:

`V=(4)/(3)\pi r^(3)`

Now to find for the radius, we need to input the value that we know into the formula.

`113.14=(4)/(3)\pi r^(3)`

Now we multiply both sides by 3/4.

`(3)/(4)x113.14=(4)/(3)\pi r^(3)`

`84.86=\pi r^(3)`

Now divide both sides by π.

`(84.86)/(\pi)=(\pi r^(3))/(\pi)`

`27.01=r^(3)`

To find r, we finally get the cube root of both sides.

`\sqrt[3]{r^(3) }= \sqrt[3]{27.01}`

r ≅ 3.00
