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