Calculate the arc length in terms of pi.(hint convert the radians to degrees)
The radius of a circle is 10 millimeters what is the length of an arc intercepted by an angle of 3/2pi?
A. (40/3)Pi mil
1m = 100cm
1cm → 0.5m
1cm → 0.5 · 100cm = 50cm
The scale: 
length = 26.8cm · 50 = 1,340cm = 13.40m
width = 12.2cm · 50 = 610cm = 6.10m
The area of the court:
A = 13.40 · 6.10 = 81.74 m²
