The area of the largest circle, that can be drawn inside a rectangle with sides 63 cm and 42 cm is \(\left(\pi=\frac{22}{7}\right)\):
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 1386 cm2
A circle inside a rectangle can be no wider than the rectangle’s shorter side, so the largest circle has a diameter equal to the shorter side, 42 cm.
Radius \(=42\div2=21\) cm
Area \(\displaystyle =\frac{22}{7}\times21\times21=22\times3\times21=1386\,\mathrm{cm^2}\)
