The volume of a cone is

So, in your case:

The

Multiply both sides by 3

Then divide both sides by 18

Then, take the square root of both sides

Since this is a distance , use the positive square root since distances can't be negative, so r = 13.

Then, the circumference of a circle is

So,

That is your answer and is an exact value since it is in terms of

See a solution process below:

If we find the distance between the center of the circle and the point on the circle we will know the radius of the circle.

The formula for calculating the distance between two points is:

Substituting the values from the points in the problem gives:

Therefore the radius of the circle is:

The equation for a circle is:

Where

And

Substituting these values gives:

First calculate the surface areas of the cone and cube.

The surface area of the cube:

We have 6 faces each having a surface area of:

Total surface area:

The surface area of a cone is given by:

We can do this by using Pythagoras's theorem.

If the slope is the hypotenuse, and the radius is one of the sides of a right triangle, then the missing side

Putting known values into the formula:

Surface area of sphere is the sum of the surface area of the cube and the cone:

Surface area of a sphere is given by:

We need to find

Divide by

Taking square root:

You can leave it in this form for an exact answer, or its approximate value of:
