Isaac is constructing a circular pool that has a diameter of 20 ft and is 5 ft deep. Part A: Find the circumference of the pool to the nearest tenth of a foot. Use 3.14 for pi. Part B: Find the area of the circle formed by the pool to the nearest foot.

The circumference of the pool is 62.8 foot long and the area of the circle formed by the pool is 314 ft².

Step-by-step explanation:

The circumference of the pool can be found by calculating the arc's length of the edges of the pool. This is done by using the following formula:

Where the radius is half the diameter, applying the data from the problem we have:

The area of the circle formed by the pool can be found using the following expression:

The circumference of the pool is 62.8 foot long and the area of the circle formed by the pool is 314 ft².
