Question

A sidewalk bounds a circular playground at GeoCity Park. Parents can exercise by walking around on

the sidewalk, while watching their children play. If the inner edge of the sidewalk is 1,256.64 meters
around, approximate the amount of area of the playground inside the circular path.

Answer 1

125,728 m²

Explanation:

C = 2 × 3.14 × r

1256.64 = 6.28r

r = 200.101910828 m

Area = 3.14 × r²

Area = 3.14 × 200.101910828²

Area = 125,728.03261143 m²
