Answer:
D) 69.08 cm
Explanation:
The circumference(C) of a circle can be determined using the below formula;
[tex]C=2\pi r[/tex]
where r = radius of the circle
pi = 3.14
Given the diameter(d) of the circle as 22cm, let's determine the radius(r) of the circle;
[tex]r=\frac{d}{2}=\frac{22}{2}=11cm[/tex]
We can substitute the given values into the formula and solve for C;
[tex]C=2*3.14*11=69.08\text{ cm}[/tex]
So the circumference of the given circle is 69.08 cm
