Answer:
157 square yards.
Step-by-step explanation:
Given:
Width of walk around a circular swimming pool = 2 yard
The diameter of the pool = 23 yard
Question asked:
What is the area of the walk ?
Solution:
<em>To find area of walk, we will first calculate area of the pool and then combined area of pool and walk then after we will subtract the area of pool from combined area.</em>
The diameter of the pool = 23 yard
Radius of the pool = 


<u>As width of walk around a circular swimming pool is 2 yard :</u>
New radius will be = 11.5 + 2 = 13.5 yard


Now, area of the walk = Combined area of pool and walk - Area of the pool
= 572.265 - 415.265
= 157 square yards
Therefore, area of the walk is 157 square yards.
