First get the semiperimeter.
Perimeter of the figure = 1/2 Circumference + the diameter.
pi = 3.14
d = 6 yds.
Circumference of the circle of a full circle = pi * d
Circumference full circle = 3.14 * 6
Circumerence full circle = 18.84 yards.
The semi circumference = 1/2 the Circumference.
The semi circumference = 1/2 18.84
The semi circumference = 9.42 yards.
That's not the complete answer.
You must add the diameter to this.
Perimeter = Semi circumference + d
Perimeter = 9.42 + 6
Perimeter = 15.42 meters
