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

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

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)

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
