Answer:
The area of road is 2310 sq.m.
Step-by-step explanation:
Radius of circular park r = 49 m
We are given that A 7m road run along a circular park of radius 49m
Width of road = 7 m
Outer radius = 49+7=56 m
Area of road = Outer area - Inner area
Area of road =
Area of road =
Area of road =2310 m^2
Hence The area of road is 2310 sq.m.
Answer:
2307.9 m²
Step-by-step explanation:
Area of the circle = π × r²
Area of the bigger circle = π × r²
= π × ( 56 m )²
= 3.14 × 3136 m²
= 9,847.04 m²
Area of the smaller circle = π × r²
= π × ( 49 m )²
= 3.14 × 2401 m²
= 7,539.14 m²
Area of the road = Area of the bigger circle - Area of the smaller circle
Area of the road = 9847.04 m² - 7539.14 m²
Area of the road = 2307.9 m²
