​

Answer 1

Step-by-step explanation:

22/7×49

154 sq.m is the area

Answer 2

$\huge{\sf{\orange{\underline{Given~:-}}}}$

• Radius = 7 m

$\huge{\sf{\orange{\underline{To~Find~:-}}}}$

• Area of circle

$\huge{\sf{\orange{\underline{Solution~:-}}}}$

Formula to find area of circle :-

$\underbrace{\overbrace{\sf\green{area \: of \: circle = \pi {r}^{2}}}}$

$\underbrace{ \sf{put \: the \: given \: values}}$

$: \implies\sf{\pi {r}^{2} }$

$: \implies\sf{ \dfrac{22}{7} \times 7 \times 7 }$

$: \implies\sf{ \dfrac{22}{ \not{7}} \times 7 \times \not{7} }$

$: \implies\sf{154 \: {m}^{2} }$
