Question

Area of circle are given 12474 sq cm find their diameter

Answer 1

Area of circle = π r²

12474 = π r²

r² = 3969

r = 63 cm.

Answer 2

The diameter of circle is 126 cm

Step-by-step explanation:

Area of circle =$\pi r^2$

Where r is the radius

We are given that Area of circle are given 12474 sq cm

So, $\pi r^2 = 12474$

$\frac{22}{7} r^2 = 12474$

$r^2 = \frac{12474 \times 7}{22}$

$r = \sqrt{\frac{12474 \times 7}{22}}$

r=63 cm

Diameter of circle = 2r = 2(63)=126 cm

Hence The diameter of circle is 126 cm
