Question

question 5 of 10
what is the approximate circumference of the circle shown below?
a. 31.4 cm
b. 20 cm
c. 62.8 cm
d. 40 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).

Step2: Substitute the radius value

Given \(r = 10\) cm and \(\pi\approx3.14\), then \(C=2\times3.14\times10\).

Step3: Calculate the result

\(C = 62.8\) cm.

Answer:

C. 62.8 cm
