The radius of the base is 
Step-by-step explanation:
we know that
The volume of a cone is equal to

we have



substitute and solve for r


![r^{2}=864/[(3.14)(7)]](https://tex.z-dn.net/?f=r%5E%7B2%7D%3D864%2F%5B%283.14%29%287%29%5D)

51:75
This is the same as 51/75.
Simplify by dividing 3 to the numerator and denominator:
17/25
Divide this to get a decimal:
17 / 25 = 0.68
Now multiply by 100 to get a percent:
0.68 * 100 = 68%
