Question

The radius of the circle is 14cm. find the circumference of the circle.​

Answer 1

Answer:

88 cm

Step-by-step explanation:

Circumference of a circle = 2πr

r = 14 cm

π = $\frac{22}{7}$

Circumference = $2 * \frac{22}{7} * 14$

= 2 * 22 * 2

= 88 cm

Answer 2

$\star \; {\underline{\boxed{\orange{\pmb{\pmb{\textbf{\textsf{ Given \;}}}}}}}}$

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

• Radius = 14cm

${\star \;{\underline{\boxed{\purple{\pmb{\pmb{\textbf{\textsf{ To\;Find \; :- }}}}}}}}}$

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

• Circumference of circle

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

$\begin{gathered}\begin{gathered} \\\end{gathered}\star \;{\underline{\boxed{\red{\pmb{\pmb{\textbf{\textsf{ SoluTion \; :- }}}}}}}}\end{gathered}$

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

❍ Formula Used

${\underline{\boxed{\pmb{\pmb{\sf{\red{ \: \sf \:Circumference \: of \: Circle}=2\pi r\: \: }}}}}}$

$\dag \;{\underline{\underline{\sf{ \; Calculating \; the \; Circumference }}}}$

${ \qquad \;{ \dashrightarrow \sf{Circumference \: of \: Circle}=2\pi r \: }}$

${ \qquad \;{ \dashrightarrow \sf{Circumference \: }=2 \: \times \frac{22}{7} \times 14\: }}$

${ \qquad \;{ \dashrightarrow \sf{Circumference \: }=2 \: \times \frac{22}{ \cancel{7}} \times \cancel{14}\:}}$

${ \qquad \;{ \dashrightarrow \sf{Circumference \: }=2 \: \times 22 \times 2}}$

${ \qquad \;{ \dashrightarrow \sf{Circumference \: }= 88}}$

$\begin{gathered}\begin{gathered}\begin{gathered} \\ \begin{gathered} \qquad \; \dashrightarrow \; \; {\underline{\boxed { \pmb{ \color{lime}{ \sf{\frak { Circumference \: of \: Circle = 88cm}}}}}}} \; \bigstar \\ \\ \end{gathered}\end{gathered}\end{gathered}\end{gathered}$

$\therefore$ Circumference of the circle is 88cm and Area of the circle is 616cm^2

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