A circular cricket field of diameter 140m, has 4 circular sit-outs of 5m radius which do not have grass. Calculate the area that has grass in the field.( π = 3.142 )
A: 15394.6
B: 314.2
C: 78.55
D: 15081.6
Find the area of the circular cricket field:
Diameter = 140m
Radius = 140 /2 = 70m
A = π r2
A = 3.142 * 70 * 70
Area of the cricket field = 15395.8 m2
Area of One Sit-out
Radius (r) of each sit-out = 5 m
Area of one sit-out
A = π r2
A = 3.142 *5 *5
A = 78.55m2
Area of Four sit-outs = area of one sit-out * 4
A = 78.55 * 4
A = 314.2m2
Area of the grass in the field
A = area of the cricket field – area of the four sit-outs
A = (15395.8 – 314.2) m2
A = 15081.6 m2
