The area of the largest circle, that can be drawn inside a rectangle with sides 63 cm and 42 cm is $\left(π=\frac{22}{7}\right)$:
Answer & explanation
Correct answer: option 1
We know that , Diameter of circle is equals to smaller dimension of rectangle .
Diameter of circle = 42 cm
Radius of circle = \(\frac{42}{2}\) = 21 cm
Area of circle = πr²
= \(\frac{22}{7}\) × 21 × 21
= 1386 cm²
