Question

find the radius of a circle if it's area is 182m

Answer 1

area of the circle is $\pi r^2$
so $\pi r^2$ =182
= $r^2$ = $\frac{182}{ \pi }$
= r = $\sqrt{57.9}$
= r = 7.6 m

Answer 2

Answer:

Radius of circle is 7.61 m .

Step-by-step explanation:

As per given information ,

Area of circle is 182 ${m}^{2}$

We have to find out the Radius of circle.

The area of circle is the region occupied by the circle.

As we know that,

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

Where,

r is a radius of circle.

Put the given values in the formula we get

$182 = \pi {r}^{2}$

$\frac{182}{\pi} = {r}^{2}$

The value of π is \frac{22}{7}

$\frac{182}{ \frac{22}{7}} = {r}^{2}$

$\frac{182 \times 7}{22} = {r}^{2}$

${r}^{2} = 57.91$

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

$r = \sqrt{57.91}$

The square root of 57.91 is 7.61

r = 7.61

Hence,

Radius of circle is 7.61 m .
