Answer:
A = 12.56 m²
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
<u>Geometry</u>
- Area of a Circle: A = πr²
- d = 2r
Step-by-step explanation:
<u>Step 1: Define</u>
d = 4 m
<u>Step 2: Find </u><em><u>r</u></em>
- Substitute: 4 = 2r
- Isolate <em>r</em>: 2 = r
- Rewrite: r = 2 m
<u>Step 3: Find Area</u>
- Substitute: A = π(2)²
- Substitute: A = (3.14)(2)²
- Evaluate: A = (3.14)(4)
- Multiply: A = 12.56 m²

as you go across the y axis the points go up by 2
Answer:
$843.44
Step-by-step explanation:
1,203.44-300=903.44
903.44-60=843.44
Answer:
Step-by-step explanation:
Complementary angles are two angles that add up to 90°.
We know the measurements of m∠ZA and m∠ZB, so their angle measures will add to 90°.
Let's simplify this equation so we have x on one side of the equation.
Now that we know the value of 
, we can substitute it inside the equation for m∠ZB (
)

-10-a/-4-(-2) = 8
-10-a / -2 = 8
-10 - a = -16
-a = -6
a=6
