Step-by-step explanation:
<u>Step 1: Define</u>
-9x + 1 = -x + 17
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 9x on both sides: 1 = 8x + 17
- Subtract 17 on both sides: -16 = 8x
- Divide 8 on both sides: -2 = x
- Rewrite: x = -2
Answer:
C. 254.34 in^2
Step-by-step explanation:
The formula for area of a circle is πr² (pi x radius x radius).
Here, only the diameter is shown.
To find the radius, divide the diameter by 2.
18 / 2 = 9
9 is the radius.
We use 3.14 as π (pi).
Now we have the final equation.
pi x radius x radius
3.14 x 9 x 9 = 254.34 in^2.
Therefore, the area of the circle is 254.34 in^2.
