Answer & Solution:
[tex]\sf \large C = 2 \pi r[/tex]
[tex]\sf \large C = (2)(3.14)(7 \: cm)[/tex]
[tex]\sf \large C = (6.28)(7 \: cm)[/tex]
[tex]\sf \large C = \boxed{ \sf 43.96 \: cm}[/tex]
↬ The circumference of the circle is 43.96 cm

Answer:
[tex] \qquad \qquad {\boxed{\orange{\pmb{\sf{Circumference\ =\ 44\ cm}}}}} [/tex]
Step-by-step explanation:
Need to FinD :
Given : We are given with a circle. The radius of the circle is 7 cm.
We need to calculate the circumference of the circle. How can we find?
We know that, the circumference of the circle is the linear distance around it or in other words, circumference is the perimeter of the circle.
So, by using a required formula, we will calculate the circumference of the circle.
[tex] \qquad \qquad \qquad {\boxed{\sf{\blacksquare\ {\red{Circumference\ =\ 2 \pi r}}}}} [/tex]
By using the above formula, which is the formula of the circumference of circle, we will calculate circumference.
[tex] \red {\frak{Where}} \begin{cases} &\sf {\pi\ is\ a\ greek\ symbol.} \\ &\sf {r\ denotes\ the\ radius.} \end{cases}[/tex]
So, by using this formula, we will calculate the circumference of the circle.
[tex] \bigstar {\underline{\underline{\red{\sf{Finding\ circumference\ of\ circle:-}}}}} [/tex]
[tex] \sf \dashrightarrow {Circumference\ =\ 2 \pi r} \\ \\ \\ \sf \dashrightarrow {Circumference\ =\ 2 \times \dfrac{22}{7} \times 7} \\ \\ \\ \sf \dashrightarrow {Circumference\ =\ \dfrac{44}{\cancel {7}} \times {\cancel {7}}} \\ \\ \\ \dashrightarrow {\underbrace{\boxed{\pink{\frak{Circumference\ =\ 44\ cm}}}}_{\sf \blue {\tiny{Required\ Solution}}}} [/tex]
∴ Hence, the required circumference of the circle is 44 cm.
