Answer:
Explanation:
The formula for the area of a circle is expressed as
Area = πr^2
Where r represents the radius of the circle
π is a constant whose value is 3.14
The area of the given circle is 78.5 square yards. To determine the radius of the circle,
πrr^2 = 78.5
3.14πr^2 = 78.5
Dividing the left hand side ofbthe equation and the right hand side of the equation by 3.14. It becomes
r^2 = 78.5/3.14 = 25
Taking square root of both sides of the equation,
r = √25 = 5 yards
