General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define</u>
Slope <em>m</em> = 1/2
Point (2, -1)
<u>Step 2: Find y-intercept </u><em><u>b</u></em>
- Substitute: y = 1/2x + b
- Substitute: -1 = 1/2(2) + b
- Multiply: -1 = 1 + b
- Isolate <em>b</em>: -2 = b
- Rewrite: b = -2
<u>Step 3: Write linear equation</u>
y = 1/2x - 2

Answer:
1. V = 37.7
2. V =603.19
Step-by-step explanation:
1. V = (3.14)×3^2 4/3
V =37.7
2. V=(3.14)×(3×4)^2 4/3
V = (3.14)×12^2 4/3
V = 603.19
