ABCD is a square of side 21 cm. A circle is inscribed in the square, which touches the sides of the square at P, Q, R and S as shown below in the figure. What is the area (in cm2) of the non-shaded region? [Figure is not drawn to scale.] $(π = \frac{22}{7})$ |
88.4 84.6 90.7 94.5 |
94.5 |
Area of square = 21 × 21 = 441 cm² Radius of circle = \(\frac{21}{2}\) = 10.5 cm Area of circle = πr² = \(\frac{22}{7}\) × 10.5 × 10.5 = 346.5 cm² Area od non - shaded region = 441 - 346.5 = 94.5 cm² |
