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
<em>From the analysis above, only option B matches the diameter with the circumference</em>

Answer:
21
Step-by-step explanation:
It is given that y varies inversely with x.
...(i)
where, k is constant of proportionality.
It is given that x=-3 when y=-105. Substitute these values in equation (i), to find the value of k.
Now,
Substitute x=15 in the above equation.
Therefore, the value of y is 21 when x=15.
The horizontal sums of the survey numbers are 200, so the numbers in the left chart are the survey values divided by 200.
The vertical sum in the first column is 188, so the first column of the right chart will be 76/188 and 112/188. Likewise, the vertical sum in the second column is 212, so the numbers will be 124/212 and 88/212.
Once you find the first number in each case, the second number is that value subtracted from 1, since the total of the two must be 1.
