Question:

Find the area of the largest circle that can be drawn inside a rectangle with sides 8m × 9m.

Options:

36 m2

50\(\frac{2}{7}\) m2

63\(\frac{9}{14}\) m2

201\(\frac{1}{7}\) m2

Correct Answer:

50\(\frac{2}{7}\) m2

Explanation:

Radius (r) of largest circle that can be drawn inside the rectangle  = \(\frac{smallest\;side}{2}\) = \(\frac{8}{2}\) = 4

Area of circle = \(\pi \) r2

                    = \(\frac{22}{7}\) × 42

                    = \(\frac{22}{7}\) × 16

                    =\(\frac{352}{7}\)

                    = 50\(\frac{2}{7}\) m2
