N would be 3. 
means the one on the left is the same as, or less than the one on the right. The one on the right is 21. N would be 3 because 7 x 3 = 21. Therefore 7n is the same as 21. 7 x 3 = 21. N=3.

We have been given that the volume of a cone is 113.04 cubic mm. We are asked to find the approximate volume of a sphere that has the same height and a circular base with the same diameter.
We know that volume of cone is .
The height is equal to the diameter. We know that diameter is 2 times radius, so we can represent this information in an equation as:
Upon substituting in volume of cone, we will get:
We know that volume of sphere is .
Upon comparing volume of cone with volume of sphere, we can see that volume of sphere is 2 times the volume of cone.
Since , so volume of sphere would be:
Therefore, volume of sphere would be 226.08 cubic mm.
For graphing, the desmos graphing calculator is a big help :))
