Question

match the circumference (rounded to the nearest meter) on the left to its corresponding circle on the right. some circumference options on the left will not be used.
36 meters
151 meters
72 meters
75 meters
38 meters
incorrect. if you know the diameter (d) of a circle, use

Explanation:

Step1: Calculate circumference for first circle

The formula for circumference of a circle is \(C = \pi d\). For the circle with \(d = 11.5\times2=23\) m, \(C=\pi\times23\approx3.14\times23 = 72.22\approx72\) m.

Step2: Calculate circumference for second circle

For the circle with \(d = 12\) m, \(C=\pi\times12\approx3.14\times12 = 37.68\approx38\) m.

Step3: Calculate circumference for third circle

For the circle with \(d=24\times 2 = 48\) m, \(C=\pi\times48\approx3.14\times48=150.72\approx151\) m.

Answer:

• \(36\) meters: Not used.
• \(151\) meters: Matches the circle with radius \(24\) m.
• \(72\) meters: Matches the circle with radius \(11.5\) m.
• \(75\) meters: Not used.
• \(38\) meters: Matches the circle with diameter \(12\) m.
