What is the area (in $\mathrm{cm}^2$) of a circle inscribed in a square of area $784 \mathrm{~cm}^2$ ? (Take $\pi=\frac{22}{7}$)

660 616 924 462

616

We have, Area of square = 784 cm2 a2 = 784 cm2 a = 28 cm Side = Diameter of circle = 28 cm Radius of circle = 14 cm Area of the circle = πr2 = \(\frac{22}{7}\) × 14 × 14 cm2 = 616 cm2
