The correct assignments are:
a. 2.5 - radius of circle A
b. 5 - diameter of circle A
c. 7.6 - radius of circle B
d. 15.2 - dircumference of circle B
e. 15.7 - circumference of circle A
f. 47.7 - circumference of circle B
How to match the numbers
In the context of circles, the relationships between radius (r), diameter (d), and circumference (C) are:
Diameter is twice the radius: d = 2r
Circumference is given by C = π d
Analysis of the options
Given that circle A is smaller than circle B, we expect the measurements for circle A to be smaller. Considering this the most likely assignments are
a. 2.5 represents the radius (half of a diameter (5)) of circle A
b. 5 represents the diameter of circle A
c. 7.6 represents the radius (15.2) of circle B
d. 15.2 - represents the radius of circle B
e. 15.7: 15.7 / π = 4.99 approximately 5
f. 47.7 : 47.7 / π = 15.18 approximately 15.2
