Answer 1

Answer:

this is your required

answer

Answer 2

$\star \; {\underline{\boxed{\red{ \pmb{\pmb{\frak{ \; Given\; \; :- }}}}}}}$

• Radius of The Sphere = 14cm .

$\begin{gathered}\begin{gathered} \\\qquad{\rule{200pt}{2pt}}\end{gathered}\end{gathered}$

$\begin{gathered} \\ \\\end{gathered}\star \;{\underline{\boxed{\pink{\pmb{\frak{ \; To \; Find\; :- }}}}}}$

• Surface Area Of Sphere = ?

$\begin{gathered} \\ \\\end{gathered}\begin{gathered}\begin{gathered} \\\qquad{\rule{200pt}{2pt}} \end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered} \\ \\\end{gathered}\star \;{\underline{\boxed{\green{\pmb{\frak{ \;Solution\; :- }}}}}}⋆\end{gathered}$

$\maltese$ Formula Used :

• ${\underline{\boxed{ \pmb{ \pmb{ \pmb{\pmb{\sf{Sphere_{(Surface Area)} = 4\pi r^2}}}}}}}}$

$\begin{gathered} \\ \\\end{gathered}\begin{gathered}\begin{gathered} \\\qquad{\rule{200pt}{2pt}} \end{gathered}\end{gathered}$

Where :

• H = Height

$\begin{gathered} \\ \\ \end{gathered}$

$\maltese$ Calculating The Area :

$\begin{gathered} \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \dashrightarrow \; \; \sf {Sphere_{(Surface Area)} = 4\pi r^2 }\end{gathered}$

$\begin{gathered} \qquad \; \dashrightarrow \; \; \sf {Sphere_{(Surface Area)} = 4 \times \frac{22}{7} \times {14}^{2} } \end{gathered}$

$\begin{gathered} \qquad \; \dashrightarrow \; \; \sf {Sphere_{(Surface Area)} = 4 \times \frac{22}{7} \times 14 \times 14} \end{gathered}$

$\begin{gathered} \qquad \; \dashrightarrow \; \; \sf {Sphere_{(Surface Area)} = 4 \times \dfrac{22} { \cancel{7}} \times \cancel{14} \times 14} \end{gathered}$

$\begin{gathered} \qquad \; \dashrightarrow \; \; \sf {Sphere_{(Surface Area)} = 4 \times 22 \times 2 \times 14} \end{gathered}$

$\begin{gathered} \qquad \; \dashrightarrow \; \; \sf {Sphere_{(Surface Area)} =88\times 28} \end{gathered}$

$\qquad \; {\dashrightarrow\; \; {\underline{\boxed{ \pmb{ \pmb{\pmb{\sf{ Sphere_{(Surface Area)} = {2464cm}^{2} }}}}} \; {\red{\pmb{\bigstar}}}}}}$

$\begin{gathered}\begin{gathered} \\ \qquad{\rule{200pt}{2pt}} \end{gathered}\end{gathered}$

$\therefore$The Surface Area of The Sphere is $\bf{2464cm {}^{2} }$

$\begin{gathered}\begin{gathered} \\ \qquad{\rule{200pt}{2pt}} \end{gathered}\end{gathered}$
