Answer 2

Jaleesa is buying a round backyard pool. The distance around the edge of the pool is 38 feet. Let π = 3.14.

Find the area that the pool will cover.

•We need to use Area = π * Radius2 but first we have to find out the Radius.

Step 1: We know Circumference = π * Diameter. Which can also be written as Circumference = π * 2 * Radius.

So 38 ft = 3.14 * 2 * Radius (So we multiply 3.14 and 2 which equals 6.28)
38 ft = 6.28 * Radius (Since 6.28 is multiplying by the Radius we need to divide by 6.28)
6.28 6.28

6.05 = Radius

Step 2: Now we can calculate the Area.
Area= 3.14 * 6.052

Area= 3.14* 36.6

Area= 114.9 ft2.
. So about 114.93
