Recall how to find the circumference of a circle:

, where  is the radius.

Using the given circumference, solve for .

Now, recall how to find the area of a circle:

Plug in the radius to find the area.

The problem is asking for us to solve for the circumference. However, the only provided information is the circle's area. In this kind of a problem, it's important think about how the provided information may relate to the information we need in order to solve for the problem. 

The area of a circle is determined through the formula: , where r is for radius. 

The circumference of a circle is determined by the formula:  where d is diameter. It can also be written as  because the radius is half the length of the diameter. 

We can now easily see that the two concepts, area and circumference, are related through the variable r. Therefore, if we can solve for r from the area, we can use that to then solve for circumference. 

Now that we have solved for the radius, we can use this value to "plug and chug" into the circumference formula and solve. 

Therefore, the circumference of the circle is .

You and your friends are ordering pizza for your Friday night Mathathon. You decide to order three pizzas, each 16" in diameter. Find the circumference of each pizza to the nearest tenth.

We are asked to find the circumference of a circle. Don't get too hungry!

We can find the circumference using the following formula:

Now, we know that 2r=d, so our formula becomes:

Simply plug in our diameter and solve for C!

So our answer is 50.3 in

Start by noticing that in the given figure, the diameter of the circle is the same as the length of a side of the square.

Use the area to find the length of a side of a square.

Next, use this to find the circumference of a circle. Recall how to find the circumference of a circle:

Find the circumference of a circle given that the distance from its center to its edge is 6.25 meters.

Find the circumference via the following:

Now, we have our radius, but the wording is a funny way of putting it. The distance from the center to any point on the edge is the same thing as a radius.

Plug in and chug to get our answer.

So, our answer is 36.27 m
