Answer : The circumference of circle is, 94.2 cm
Explanation :
Formula used for circumference of circle is:
Circumference of circle = [tex]2\pi r[/tex]
where,
r = radius of circle
Given:
Diameter of circle = 30 cm
Radius of circle = [tex]\frac{Diameter}{2}=\frac{30cm}{2}=15cm[/tex]
Now we have to determine the circumference of circle.
Circumference of circle = [tex]2\pi r[/tex]
Circumference of circle = [tex]2\times 3.14\times (15cm)[/tex]
Circumference of circle = 94.2 cm
Therefore, the circumference of circle is, 94.2 cm
