Question

suppose the radius of a circle is 8 units. what is its circumference? use 3.14 for π and enter your answer as a decimal. units

Explanation:

Step1: Recall the formula for the circumference of a circle

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

Step2: Substitute the given values into the formula

We are given that the radius \( r = 8 \) units and \( \pi = 3.14 \). Substituting these values into the formula, we get:
\( C = 2\times3.14\times8 \)

Step3: Perform the multiplication

First, calculate \( 2\times3.14 = 6.28 \). Then, multiply this result by 8: \( 6.28\times8 = 50.24 \).

Answer:

50.24
