Question

1. darrel drew the circle below.

what is the approximate circumference of the circle darrel drew?
a. 11 inches
b. 22 inches
c. 24.5 inches
d. 38.5 inches

Explanation:

Step1: Identify the radius

The distance from the center to the circle (radius \( r \)) is 3.5 inches.

Step2: Recall the circumference formula

The formula for the circumference \( C \) of a circle is \( C = 2\pi r \). We can use \( \pi \approx \frac{22}{7} \) for approximation.

Step3: Substitute values into the formula

Substitute \( r = 3.5 \) and \( \pi \approx \frac{22}{7} \) into the formula:
\( C = 2\times\frac{22}{7}\times3.5 \)
First, simplify \( 3.5=\frac{7}{2} \), so:
\( C = 2\times\frac{22}{7}\times\frac{7}{2} \)
The \( 2 \) and \( \frac{7}{2} \) (or the \( 7 \) in numerator and denominator) cancel out, leaving \( C = 22 \) inches.

Answer:

B. 22 inches
