Question

what is the circumference of the following circle? use 3.14 for π and enter your answer as a decimal.

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: Identify the radius and the value of \( \pi \).

From the problem, the radius \( r = 7 \) and \( \pi = 3.14 \).

Step3: Substitute the values into the formula.

Substitute \( r = 7 \) and \( \pi = 3.14 \) into the formula \( C = 2\pi r \):
\( C = 2\times3.14\times7 \)

Step4: Calculate the result.

First, calculate \( 2\times3.14 = 6.28 \). Then, calculate \( 6.28\times7 = 43.96 \).

Answer:

43.96
