Question

Find the circumference of the circle below. Use 3.14 for πA) 379.94 cmB) 138.16 cmC) 34.54 cmD) 69.08 cm

Answer 1

D) 69.08 cm

Step-by-step explanation:

The circumference(C) of a circle can be determined using the below formula;

`C=2\pi r`

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;

`r=(d)/(2)=(22)/(2)=11cm`

We can substitute the given values into the formula and solve for C;

`C=2*3.14*11=69.08\text{ cm}`

So the circumference of the given circle is 69.08 cm
