Question

what is the approximate circumference of the circle shown below? a. 22 cm b. 28 cm c. 44 cm d. 14 cm

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference of a circle is $C = 2\pi r$, where $r$ is the radius of the circle.

Step2: Identify the radius value

The radius $r = 7$ cm as given in the problem.

Step3: Substitute the radius into the formula

$C=2\times\pi\times7=14\pi$ cm. Taking $\pi\approx 3.14$, we have $C\approx14\times3.14 = 43.96\approx44$ cm.

Answer:

C. 44 cm
