Answer:
B. 19 inches and 60 inches
Explanation:
This is the most reasonable approximation for the diameter and circumference. The formula for finding the circumference of a circle when the diameter is known is πd. π is around 3.14, so take each diameter and multiply it by three to estimate the value of the circumference.
A. 5 meters (diameter) and 22 meters (circumference)
5 * 3 = 15
15 is pretty far off from 22 on a similar scale. It's negotiable.
B. 19 inches (diameter) and 60 inches (circumference)
19 * 3 = 57
57 is really close to 60. This is most definitely one of the selected pairs!
C. 33 centimeters (diameter) and 80 centimeters (circumference)
33 * 3 = 99
99 seems a bit off from 80 to me. Your call.
The answer says select all the pairs that could be reasonable, and B is the answer that stood out the most to me. You can decide if any of the other pairs meet the requirement.
Hope this helps!
