Answer 1

by equating formula u will get answer

Answer 2

$\huge \red{ \mathfrak{solution}}$

To find the Radius of the circle .

Given:

Area of the circle = 154m^2

As we know that,

Area of circle =

$\huge \boxed{\pi {r}^{2} }$

Now substitute the value of area

$\rightarrow \: 154 = \pi {r}^{2} \\ \\ \rightarrow \: 154 = \frac{22}{7} {r}^{2} \\ \\ \rightarrow \: {r}^{2} = \frac{154 \times 7}{22} \\ \\ \rightarrow \: {r}^{2} = 49 \\ \\ \rightarrow \: r = \sqrt{49} \\ \\ \rightarrow \: r = 7$

Hence, the value of radius of circle is

$\huge \purple{ \boxed{7m}}$
