ANSWER
EXPLANATION
The circumference of a circle is calculated using the formula:

From the question, the radius of the circle is 10 inches.
We substitute the radius into the formula to get:

Let us multiply out to get:

The question required that we leave the answer in terms of π.
The correct choice is C.
Answer:
The solution is: (x, y) = (9, -7)
Step-by-step explanation:
Step 1: Solve one of the equations for either x = or y = . We will solve second equation for y.
x+y=3
y=3-x
Step 2: Substitute the solution from step 1 into the second equation.
3x+4(3-x)=5
Step 3: Solve this new equation.
3x+4(3-x)=5
3x+12-4x=3
-x+12=3
-x=3-12
x=9
Step 4: Solve for the second variable
y=3-x
y=3-9
y=-7
The solution is: (x, y) = (9, -7)
The x intercept would be 2/4x and the y would be 2:)
