Question

1. find the circumference of both circles to the nearest hundredth.

22 m
the circumference of the blue circle is about □ m.
the circumference of the green circle is about □ m.

Explanation:

Step1: Identify blue circle radius

The blue circle's radius $r_b = \frac{22}{2} = 11$ m

Step2: Calculate blue circle circumference

Use formula $C=2\pi r$.
$C_b = 2\pi \times 11 = 22\pi \approx 69.1150$ m

Step3: Round blue circumference to nearest hundredth

$C_b \approx 69.12$ m

Step4: Identify green circle radius

The green circle's radius $r_g = 22$ m

Step5: Calculate green circle circumference

$C_g = 2\pi \times 22 = 44\pi \approx 138.2301$ m

Step6: Round green circumference to nearest hundredth

$C_g \approx 138.23$ m

Answer:

The circumference of the blue circle is about 69.12 m.
The circumference of the green circle is about 138.23 m.
