hope this helps.
if you ever need helping with graph, Desmos graphing calculator is really helpful. (its a website, just search it up)
Answer and Step-by-step explanation:
If 10 is the given radius, then we can plug it into the circumference formula.
C = 2πr
C = 2π(10)
C = 20π
Now use a calculator to evaluate 20π.
You should get: 62.83185307179586476925286766559
Now, round to the nearest tenth (aka, the first decimal place after the decimal.
C ≈ 62.8
That is your answer.

The equation of the line would be y = -3x + 3
The x intercept is when y is equal to 0.
To solve for the x intercept, plug 0 in for y and then solve
0 = -3x + 3
0-3 = -3x +3 -3
-3 = -3x
-3/-3 = -3/-3x
1 = x
The x intercept is (1,0)
Answer:
A real solution in algebra is simply a solution to an equation that is a real number.
for example
If y>0, then x2 = y has two real solution or roots. x = ±√y
If y=0, then x2 = y has one real solution.
Actually the answer would be 18.
