A path 7m wide surrounds a circular lawn whose diameter is 252m find the area of the path?
Answer:
Area of path = π(R-r)(R+r)
Radius inner circle = 126 (252/2)
Radius outer circle = 126+7 = 133
Therefore,
Area of path = 22/7(133-126)(133+126)
= 22/7(7)(259)
= 22/7(1813)
= 39886/7 = 5698 Sq.cm
Radius inner circle = 126 (252/2)
Radius outer circle = 126+7 = 133
Therefore,
Area of path = 22/7(133-126)(133+126)
= 22/7(7)(259)
= 22/7(1813)
= 39886/7 = 5698 Sq.cm
