Answer:
The answer is B
Step-by-step explanation:
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:
c

C.D.
Answer:
If A = 8, B = 5
If A = 20, B = 3
Step-by-step explanation:
4x²(2x³ + 5x)
8x⁵ + 20x³
If A = 8, B = 5
If A = 20, B = 3
