Question

A circular path around a circular Park .circumference of circular park is the 110 m and circular path is 220 m find the width of the path also find the area of the park

Answer 1

Answer:C = 2 PIE r

110m = 2 ×22÷7×r

110m= 44÷7 ×r

110×7÷44 =r

70m =r

C =2 PIE r

220=2×22÷7×r

220×7÷44 =r

140m =r

Width of the ring = bigger radius - smaller radius

140-70 m =70m

Area of the ring = area of outer circle

- Area of inner circle

Area of outer cirl = PIE r sq.

22/7×140 ×140

61600

Area.of inner circle = P8E r sq.

22/7×70×70

15400

Area of the ring = 61600- 15400
