Question

question 2 of 10
what is the approximate circumference of the circle shown below?
a. 48.8 cm
b. 19.2 cm
c. 76.6 cm
d. 38.3 cm

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference of a circle is \(C = \pi d\), where \(d\) is the diameter.

Step2: Identify the diameter

From the problem, the diameter \(d = 12.2\) cm.

Step3: Calculate the circumference

Substitute \(d = 12.2\) into the formula: \(C=\pi\times12.2\). Using \(\pi\approx3.14\), we get \(C\approx3.14\times12.2 = 38.308\approx38.3\) cm.

Answer:

D. \(38.3\) cm
