Question

the circumference of circel whose radius is 7​

Answer 1

Answer:

circumference of the circle is 2πr

radius of circle is=7

circumference of circle=2π ×7

=2×22/7×7

=44ans

Answer 2

Answer:

Circumference of the given circle (C) = 44 cm

Step-by-step explanation:

Given radius of a circle(r)=7 cm

)* We know that,

$\begin{gathered}\boxed {Circumference \:of \: a \: circle (C)\\=2\pi r }\end{gathered}$

Now,

$\begin{gathered}C = 2\times \frac{22}{7} \times 7\:cm \\=2 \times 22 \:cm\\=44\:cm\end{gathered} </p><p>C=2× </p><p>7</p><p>22</p><p> </p><p> ×7cm</p><p>=2×22cm</p><p>=44cm</p><p> </p><p> </p><p>$

Therefore,

Circumference of the given circle (C) = 44 cm
