Area of a circular park = 5544m²
πr² = 5544m²
22/7*r² = 5544
r²= 5544 * 7/22
r² = 1764
r = √1764
r = 42m
Width of the circular path = 7 m
. °. Radius of the circular park including path (R) = 42 + 7= 49 m
. °. Area of the circular path = Area of the circular park with path - Area of the circular park
= πR²-πr²
=π ( R² - r²)
= π(49²-42²)
=π(2401-1764)
=π*637
=22/7*637
=2002m²
