The difference in the area of circle and square is # 529# sq.cm

Explanation:

#1.76m =176 cm#
The sides of the square formed is #s=176/4 = 44 cm #
Area of the square formed is #A_s = s^2=44^2=1936#sq.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]
