Answer:
63.6 m^2
Step-by-step explanation:
A = (pi)r^2
r = d/2 = 9 m / 2 = 4.5 m
A = (3.142)(4.5 m)^2
A = 63.6 m^2
Answer:

General Formulas and Concepts:
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
(4x² - 2x - 3) + (-3x² + x + 7)
<u>Step 2: Simplify</u>
- Combine like terms (x²): x² - 2x - 3 + x + 7
- Combine like terms (x): x² - x - 3 + 7
- Combine like terms (Z): x² - x + 4
Answer:
The slopes are neither perpendicular nor parallel.
Step-by-step explanation:
First we are going to find the slope-inercept form from the equation, -2x + 10y = 5.
Solve for y.
-2x + 10y = 5
<u>+2x. =</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>+2x</u>
10y = 2x + 5

So we now have

Looking at the equation above, the slopes are neither perpendicular nor parallel.
