area of circular sheet with radius 3m = πr^2 = 9π m^2
area of circle with radius 2m = πr^2 = 4π m^2
area of remaining sheet = area of circular sheet(3m) -area of circle (2m) = 9π - 4π = 5π = 5×3.14 = 15.7 m^2
area of circle with radius 2m = πr^2 = 4π m^2
area of remaining sheet = area of circular sheet(3m) -area of circle (2m) = 9π - 4π = 5π = 5×3.14 = 15.7 m^2
