Question

Length of rectangle is 42 cm and its width is 48 cm. Calculate the area of the biggest circle which can be drawn inside it?

Answer 1

Answer:

Answer is a=πr2

=22/7×21×21

=22×3×21

1386cm2

Answer 2

The area of circle would be 3193.29 sq. cm.

Step-by-step explanation:

Since we have given that

Length of rectangle = 42 cm

Breadth of rectangle = 48 cm

So, the diameter of circle = length of diagonal.

So, the length of diagonal would be

$\sqrt{l^2+b^2)}=\sqrt{42^2+48^2}\\\\=63.78$

So, the radius of circle = $\dfra{63.78}{2}=31.89\ cm$

So, the area of circle would be

$\pi r^2\\\\=3.14\times (31.89)^2\\\\=3.14\times 1016.97\\\\=3193.29\ cm^2$

Hence, the area of circle would be 3193.29 sq. cm.
