Answer:
C. The ratio of the area to the circumference is equal to half the radius.
Step-by-step explanation:
The area of a circle can be written as;
Area A = πr^2
The circumference of a circle is;
Circumference C = 2πr
Using the formula, w can derive the relationship between the two variables.
A = kC
k = A/C
Substituting the two formulas;
k = (πr^2)/(2πr) = r/2
So,
A = (r/2)C
A/C = r/2
The ratio of the area to the circumference is equal to half the radius.
Given;
Area = 200.96
Circumference = 50.24
Radius = 8
To confirm;
k = r/2 = 8/2 = 4
Also,
A/C = 200.96/50.24
A/C = 4

Answer:
The avergae temp rose 51° F.
Step-by-step explanation:
Average temp in January = -8°F
Average temp in March = 43°F
-8 is 8 away from 0 (absolute value)
43 is 43 away from 0 (absolute value)
43 + 8 = 51
The average temp rose 51°F
A constant function is a function whose output value f(x) is the same for every input value x, i.e. for all x, f(x)=c.
This means that
