Question

c = 2\pi r
monique is painting a circle on the lunchroom wall. the radius of the circle is 3 feet.
what is the approximate circumference of moniques circle? (use 3.14 for \pi.)
a. 9.42 feet
b. 18.84 feet
c. 28.26 feet
d. 37.68 feet

Explanation:

Step1: Identify values

Given $r = 3$ feet and $\pi=3.14$, and the formula $C = 2\pi r$.

Step2: Substitute values

$C=2\times3.14\times3$.

Step3: Calculate result

$C = 18.84$ feet.

Answer:

B. 18.84 feet
