Question

Okay guys, I’m going to need your help today.As always, no false answers, and do it CORRECTLY, you get brainliest!Here it goes:
Select all the pairs that could be reasonable approximations for the diameter and circumference of a circle.

5 meters and 22 meters

19 inches and 60 inches

33 centimeters and 80 centimeters

10 feet and 31 feet

3 inches and 9.5 inches

Answers

  1. Answer:
    B. 19 inches and 60 inches.
    Step-by-step explanation:
    Required
    Select matching pairs
    Represent diameter with D and Circumference with C
    C is calculated as:
    Where
    A. D = 5m; C = 22m
    Using:
    15.71 does not approximates to 22m.
    Hence, the pair do not match
    B. D = 19 in; C = 60 in
    Using:
    59.698 approximates to 60.
    Hence, the pair match
    C. D = 33 cm; D = 80 cm.
    Using:
    103.686 does not approximates to 22m.
    Hence, the pair do not match
    From the analysis above, only option B matches the diameter with the circumference

  2. Answer:
    19 inches and 60 inches
    10 feet and 31 feet
    3 inches and 9.5 inches
    Step-by-step explanation:
    formula to find circumference is:
    radius x 2 x pi (3.14)
    or
    diameter (radius x 2) x pi (3.14)
