Your explanation is here.

Answer 2

Answer:

Circumference of circle is 17.58 m.

Step-by-step explanation:

As per given information ,

Area of circle is 24.64 ${m}^{2}$

We have to find out the circumference of circle.

As we know that,

Area of circle $= \pi {r}^{2}$

Put the given values in the formula we get

$24.64 = \pi {r}^{2}$

$\frac{24.64}{\pi} = {r}^{2}$

The value of π is 3.14 .

$\frac{24.64}{3.14} = {r}^{2}$

${r}^{2} = 7.84$

When square is shift from left to right side it becomes square root.

$r = \sqrt{7.84}$

The square root of 7.84 is 2.8 .

r = $2.8$

Radius = r = 2.8 m

Circumference of circle = $2 \times \pi \times r$

Put the value of r ,

Circumference of circle = $2 \times \pi \times 2.8$

Circumference of circle = $5.6\times \pi$

Put the value of π = 3.14

Circumference of circle = $5.6 \times 3.14$

Circumference of circle = $17.58$

Hence,

Circumference of circle is 17.58 m.
