Area of a semicircle = 1/2 πr²
----------------------------------------------------
Find Radius:
----------------------------------------------------
1/2πr² = 76.97
r² = 76.97 ÷ 1/2π
r³ = 49
r = √49
r = 7
----------------------------------------------------
Find Diameter:
----------------------------------------------------
Diameter = Radius x 2
Diameter = 7 x 2
Diameter = 14 yards
----------------------------------------------------
Answer: 14 yards
