Question

question 3 of 10 which is the best estimate of the circumference of this circle? 2 a. 4 units b. 38 units c. 12 units d. 2 units

Explanation:

Step1: Recall circumference formula

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

Step2: Identify radius value

From the picture, the radius $r = 2$ units.

Step3: Calculate circumference

Substitute $r = 2$ into the formula: $C=2\pi r=2\pi\times2 = 4\pi$. Using an approximation of $\pi\approx3$, we get $C\approx4\times3=12$ units.

Answer:

C. 12 units
