Hello dear,

Area of circle = 24.64m²

=> πr² = 24.64

=> 22/7 × r² = 24.64

=> r² = 24.64 × 7/22

=> r² = 7.84

=> r = 2.8

radius = 2.8m

Now,

Circumference of circle = 2πr

= 2 × 22/7 ×2.8
= 1.76m

Hope it helps.

The circumference of circle is 17.6 m.

Step-by-step explanation:

Given,

The area of circle = 24.64m^2

To find, the circumference of the circle = ?

Let the radius of circle = r

We know that,

The area of circle =\pi r^2

\pi r^2=24.64

\dfrac{22}{7}\times r^2=24.64

r^2=\dfrac{24.64\times 7}{22} = 1.12\times 7

r^2=7.84

r^2=2.8^2

⇒ r = 2.8 cm

∴ The circumference of circle =2\pi r

= 2\times \dfrac{22}{7} \times 0.4

= 2\times 22 \times 0.4

= 17.6 m

Hence, the circumference of circle is 17.6 m.
