Answer» Given : The high school stadium contains a track that surrounds a soccer field. The soccer field is 100 YARDS long and 70 yards wide. The school decided to cover the semicircles with GRASS to create a space for stretching and other activities. To Find: area of one of the semicircles at either END of the track How many square yards of grass will the school need to cover the entire circle? Solution: Diameter of SEMICIRCLE = 70 yards Radius of semicircle = 70/2 = 35 yards Area of semicircle at one end = (1/2)πr² = (1/2)(22/7)35² = 1,925 sq yards area of one of the semicircles at either end of the track = 1,925 sq yards square yards of grass will the school need to cover the entire circle = 2 x 1,925 = 3850 sq yards distance around one of the semicircles at either end of the soccer field = πr = (22/7) 35 = 110 yards distance around the inner lane of the track = 100 + 100 + 110 + 110 = 420 yards Learn More: Jawaharlal Nehru Stadium in New Delhi is conducting the annual ... .
