Remember, a negative times a negative equals a positve.
Answer:
r ≅ 3.00
Step-by-step explanation:
First we need to get the formula for finding the volume of sphere. The formula is:

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

Now we multiply both sides by 3/4.


Now divide both sides by π.


To find r, we finally get the cube root of both sides.
![\sqrt[3]{r^{3} }= \sqrt[3]{27.01}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Br%5E%7B3%7D%20%7D%3D%20%5Csqrt%5B3%5D%7B27.01%7D)
r ≅ 3.00
I believe it is -2. Hope it helps!
