The radius of a circle is 49m. There is7m wide road round, it on theoutside. Find the area of the road?​

Answer»

Step-by-step EXPLANATION:

Radius of the ROAD = Radius of CIRCLE + 7m

Therefore, Radius of road = 56m

Area of circle =

\pi \:  {r }^{2}

22/7 × 49 × 49

= 7546 m2

Area of CIRCULAR road = 22/7 × 56 × 56

= 9856m2

Area of the road (only) = Area of circular road - Area of circle

= 9856 - 7546

= 2310m2
