The difference in the area of circle and square is 529529 sq.cm

Explanation:

1.76m =176 cm1.76m=176cm
The sides of the square formed is s=176/4 = 44 cm s=1764=44cm
Area of the square formed is A_s = s^2=44^2=1936As=s2=442=1936sq.cm

The radius of the circle formed is r=(2 pi r)/ (2pi) ; 2 pi r =176 :. r= 176/(2pi) =28 .01 (2dp) cm

Area of circle formed is pi *r^2 = pi *28.01^2 = 2465 sq.cm

Area of the square formed is 1936 sq.cm
Area of circle formed is is 2465 sq.cm

The difference in the area of circle and square is (2465-1936)= 529 sq.cm [Ans]
