You want to install a 2 yd wide walk around a circular swimming pool. The diameter of the pool is 23 yd. What is the area of the walk? Use 3.14 for pi.

The area of the walk is 157 yds²

Step-by-step explanation:

The area of the walk = total area of the swimming pool and the walk - area of the swimming pool.

The formula for determining the area of a circle is expressed as

Area = πr²

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

Considering the swimming pool,

Diameter = 23 yds

Radius = diameter/2 = 23/2 = 11.5 yds

Area = 3.14 × 11.5² = 415.265 yds²

Considering the swimming pool and the walk,

Radius = 11.5 + 2 = 13.5 yds

Area = 3.14 × 13.5² = 572.265 yds²

Therefore, area of the walk is

572.265 - 415.265 = 157 yds²

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
