How can I find the radius of a cone ? If not given the volume ?

V=C∗pi∗r2=C′∗r2

Step-by-step explanation:

V=pi∗r2∗h/3

Since the height is known, we can substitute it with an arbitrary constant:

V=C∗pi∗r2=C′∗r2

Now we have volume in terms of the radius, which are both unknown. Unless we are given information on how any of these variables are related, we cannot solve for the radius in this problem.

the solution is h=10 because you add 9 to each side of the equation.
