Question

1. a circular fountain has a diameter of 6 units. which value best approximates the circumference?

a. 9 units
b. 18 units
c. 19 units
d. 38 units

Explanation:

Step1: Recall circumference formula

The formula for the circumference of a circle is $C = \pi d$, where $d$ is the diameter.

Step2: Substitute diameter value

Substitute $d = 6$ into the formula:
$C = \pi \times 6$

Step3: Approximate the value

Use $\pi \approx 3.14$, so $C \approx 6 \times 3.14 = 18.84$

Answer:

C. 19 units
