Aswimming pool has a diameter of 32 feet. what is the area of the swimming pool that needs to be covered by a tarp?

To get the area of a circle, use this formula: A =  * radius^2

We can use 3.14 for .
And because this formula uses the radius and not the diameter, we will need to convert the diameter into a radius. The radius is half of a diameter.

32 / 2 = 16

Now we have our radius.

A = 3.14 * 16^2
A = 3.14 * 256
A = 803.84

So, you will need to have a tarp that is at least 803.84 feet squared to cover the pool.
