For this case we have that the area of a circle is given by:

Where:
r: It is the radius of the circle
By clearing the radio we have:

We take the positive value:

The diameter is twice the radius:

Answer:

5 = what percent of 23
5 = x% of 23
5 = (x/100)*23
5 = 23x/100
5*100 = 23x
23x = 5*100
x = 5*100/23
x = 21.739
5 is ≈ 21.739% of 23
A. 0.250006, 0.250007, 0.250008
b. 0.3330001, 0.3330002, 0.3330003
Answer:
D. 62.5
Step-by-step explanation:
2 ways
1.
7.5 ÷ 3 = 2.5
25 times 2.5 = 62.5
2.
3/7.5 = 25/x
3x = 187.5
187.5 ÷ 3 = 62.5
Answer:
2
Step-by-step explanation:
r(x) = 2 sqrt(x)
s(x) = sqrt(x)
r(x) / s(x) = 2 sqrt(x) / sqrt(x)
= 2
