The diameter of the circle is 14 cm. Then find the area of the circle

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

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

• Diameter of the circle =14 cm

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

${\orange {\boxed {\boxed {\pmb {\blue {r=\dfrac{D}{2}}}}}}}$

$\sf \leadsto r=\dfrac{14}{2}$

$\sf \leadsto r=\dfrac{\cancel{14}}{\cancel{2}}$

$\leadsto{\orange {\boxed {\green {\tt {r=7\:cm}}}}}$

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

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

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

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

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

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

Answer 2

Given:-

$\tt \: Diameter= 14cm \\ </h2><h2> \tt \: Radius= \frac{14}{2} = 7 \: cm$

Formula:-

$\tt \: Area \: \: of \: \: circle=\pi {r}^{2} \\ \tt = \frac{22}{7} \times 7 \times 7 \\ \tt = 154 \: {cm}^{2}$
