Answer:
12.56 square yards
Explanation:
From the question we are given;
the diameter of a circular patio as 4 yards
but, radius = diameter/2
= 2 yards
We are required to calculate the area of the patio
Area of a circle = πr²
Therefore;
Area= 3.14 ×2²
=12.56 square yards
Thus, the area of the patio is 12.56 square yards
