Question

The area of the largest circle that can be drawn inside a rectangle with sides $18$ cm and $14$ cm is

• A. 49 $c{m}^2$
• B. 154 $c{m}^2$
• C. 378 $c{m}^2$
• D. 1078 $c{m}^2$

Answer 1

The correct option is B 154 $c{m}^2$

The diameter of the circle = breadth of the rectangle = $14cm$.
Hence the radius of the circle = $7cm$.
The area of the circle = $\pi r^2=\frac{22\times 7\times 7}{7}=154{cm}^2$
