A circular grass lawn of 35 metres in radius has a path 7 metres wide running around it on the outside. Find the area of path.	Choose the correct choice.
A) 1694 m2  B) 1700 m2  C) 1598 m2  D) 1500 m2  E) None of thes
Radius of a circular grass lawn (without path) = 35 m   ∴ 1694 m2rea = πr2 = π(35)2   Radius of a circular grass lawn (with path)   = 35 + 7= 
<gadget id="calculator">35 + 7</gadget>
<output>42</output>
42 m   ∴ 1694 m2rea= πr2 = π(42)2   ∴ 1694 m2rea of path = π(42)2 – π(35)2   = π(422 – 352) = π( 42 + 35)(42 – 35)   1694 m2nswer 1694 m2
