Answer : The circumference of circle is, 94.2 cm

Explanation :

Formula used for circumference of circle is:

Circumference of circle = $2\pi r$

where,

r = radius of circle

Given:

Diameter of circle = 30 cm

Radius of circle = $\frac{Diameter}{2}=\frac{30cm}{2}=15cm$

Now we have to determine the circumference of circle.

Circumference of circle = $2\pi r$

Circumference of circle = $2\times 3.14\times (15cm)$

Circumference of circle = 94.2 cm

Therefore, the circumference of circle is, 94.2 cm
