(c) Circumference of the circle
= π × diameter
= $\frac{22}{7}\times 56$ = 176 cm
∴ Perimeter of the square= (272 – 176 ) = 96 cm
∴ Side of the square = $\frac{96}{4}$ = 24 cm
∴ Area of the square= (24 × 24) = 576 sq cm
∴ Area of the circle = π${\mathrm{r}}^2$
= $\frac{22}{7}\times 28\times 28=2464$ sq.cm
∴ Required sum
= (576 + 2464) sq cm = 3040 sq cm
