Ответ:
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
Ответ:
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)
