Circumference of circle = 2pπr = 44
⇒ 2 × $\frac{22}{7}$ × r = 44
⇒ r = $44\times 7*/2\times 22$ = 7 cm
Area of circle = $\mathit{\pi }{\mathit{r}}^2$
= $\frac{22}{7}$ × 7 × 7
= 154 sq. cm.
Perimeter of square = 44 cm.
Side of square = $\frac{44}{4}$ = 11 cm
Area of square = 11 × 11
= 121 sq. cm.
Difference = 154 – 121
= 33 sq. cm.
