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

because after that you would subtract by 20
Answer:
SU = 22
Step-by-step explanation:
SR = RU
4x - 1 = x + 8
3x - 1 = 8
3x = 9
x = 3
SR = 4(3) - 1 = 11
RU = 3 + 8 = 11
SU = 11 + 11 = 22
16.45 - 6.4 = 10.05kg of flour to make 15 batches of scones
1 batch = 10.05/15
= 0.67kg of flour.
