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 .
