Question

monique is painting a circle on the lunchroom wall. the radius of the circle is 3 feet. what is the approximate circumference of monique’s circle? (use 3.14 for π.) a. 9.42 feet b. 18.84 feet c. 28.26 feet d. 37.68 feet

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 \( r = 3 \) feet and \( \pi \approx 3.14 \). Substituting these values into the formula, we get:
\( C = 2\times3.14\times3 \)

Step3: Perform the calculation

First, calculate \( 2\times3 = 6 \). Then, multiply this result by \( 3.14 \):
\( 6\times3.14 = 18.84 \) feet.

Answer:

B. 18.84 feet
