The drawing below (not to scale) shows a running track. The ends are semicircles. The distance between the two inner parallel straight lines is 60 meters, and they are each 100 meters long. The track is 10 meters wide.Find the area of the actual track.(Shaded region)
Question
Answer:
100×10×2=200060+10+10=80
80/2=40
40²π=1600π
60/2=30
30²π=900π
1600π-900π=700π
Area of shaded region=700π+2000
