Answer:
3.15cm
Step-by-step explanation:
1. Determine where the given numbers go in formula for the volume of the cone.
2. Multiply ⅓ and 12cm to get 4
3. Isolate the section with unknown variables by dividing 125 and 4 to get 31.25 (rounded)
4. Now isolate the r² by dividing π by 31.25 to get 9.95
5. Take the square root of r and 9.95 to get rid of the exponent.
6. The radius is the answer of square rooting 9.95
7. If asked to check your answer, fill in the formula for the volume of the cone with the radius and round the answer to see if you get the volume you were originally given.
Hope this helps! :)
