The radius of the circle is 7 cm. Then find the area of the circle

${\bf {\huge {\pink{\underline {\dag{\red {AnSwEr}}}}}}}$

${\mathfrak {\large {\pink {\underline {\dag {\red {GiVeN}}}}}}}$

• Radius of the circle =7 cm

${\mathfrak {\large {\pink {\underline {\dag {\red {SoLuTiOn}}}}}}}$

${\orange {\boxed {\boxed {\pmb {\blue {A=\pi {r}^{2}}}}}}}$

$\sf \leadsto A=\dfrac{22}{7}\times {\big(7\big)}^{2}$

$\sf\leadsto A=\dfrac{22}{7}\times 7\times 7$

$\sf\leadsto A=\dfrac{22}{\cancel{7}}\times \cancel{7}\times 7$

$\sf\leadsto A=22\times 7$

$\leadsto{\orange {\boxed {\green {\tt {A=154\:{cm}^{2}}}}}}$

Answer 2

Answer:

$area \: of \: circle = π r²$

$⠀⠀⠀⠀⠀⠀⠀⠀ = \frac{22}{7}$ $\times 7\times 7$

$⠀⠀⠀⠀⠀⠀⠀⠀= 22 \times 7$

$⠀⠀⠀⠀⠀⠀⠀⠀= 154$

The area of circle is 154 cm²
