Answer:

Circumference of circle is 282.6 cm .

Step-by-step explanation:

Formula

[tex]Circumference\ of\ a\ circle = 2\pi r[/tex]

Where r is the radius of the circle .

As given

Radius of a circle is 45 cm .

[tex]\pi = 3.14[/tex]

Putting values in the above

[tex]Circumference\ of\ a\ circle = 2\times 3.14\times 45[/tex]

                                                    = 282.6 cm

Therefore the circumference of circle is 282.6 cm .
