If the volume of the crystal ball is about 113.14 cm3, the radius of the ball is approximately
stellarik [79]

Answer:

r ≅ 3.00

Step-by-step explanation:

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

V=\frac{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=\frac{4}{3}\pi r^{3}

Now we multiply both sides by 3/4.

\frac{3}{4}x113.14=\frac{4}{3}\pi r^{3}

84.86=\pi r^{3}

Now divide both sides by π.

\frac{84.86}{\pi}=\frac{\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
