To solve this problem, use formula of Circumference of circle. It is given as,

  • Circumference of circle equal to 2πr, where 'r' is radius & π is 22/7 or 3.14

  • Circumference of circle = Perimeter of circle

\\

Given radius, (r) = 7 unit

  • Calculate circumference of circle

 \implies{ \pmb{ \sf 2\pi r}} \\  \\    {\underline{ \pmb{ \tt{Substitute \: the \: value \: of \: radius(r)}}}} \\  \\  \implies \sf 2  \times \dfrac{22}{ \cancel 7}  \times {  \cancel{7}} \\  \\  \implies \sf 2 \times 22 \\  \\  \implies\sf 44\:unit \\ \\  \quad\therefore\sf Required \: circumference \: of \: circle \: {\pmb{\sf{ 44  \: unit}}}

Answer:

Circumference of circle is 43.96 .

Step-by-step explanation:

As per given information ,

Radius of circle is 7 .

We have to find out the circumference of circle.

The circumference means the length of the complete arc of a circle.

As we know that,

Circumference of circle = 2 \times \pi \times r

Where,

r is a radius of circle.

Put the value of r ,

Circumference of circle = 2 \times \pi \times 7

Circumference of circle =  14\times \pi

Put the value of π = 3.14

Circumference of circle = 14 \times 3.14

Circumference of circle = 43.96

Hence,

Circumference of circle is 43.96 .
