From a corner of a ground of 20m*30m, a boy hits a ball that travels maximum 14m. What is the area of the football ground through which the ball can pass by the hit of that boy from that corner ?	Select:
A) 132
B) 140
C) 150
D) 154
E) 168
Area covered by ball = Pi*r^2/4 ( here we divide by 4 because ball is hit from the corner of the ground and only 1/4 part the ball can go)   where r= 14 m = length of pass   So area = (22/7)*14*14/4=
