Base + lateral area:
Base = pi*6^2 = 36*pi
Lateral area=pi*r*l (nice formula) = pi*6*12 = 72*pi
TOTAL = 108*pi = 339.29200658769764
Nearest hundredth: 339.29
Answer:
y = 3x + 2
Step-by-step explanation:
Convert the equation to slope intercept form to get y = –1/3x + 2. The old slope is –1/3 and the new slope is 3. Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b or 5 = 3(1) + b, so b = 2
So y = 3x + 2
The last 3 numbers are the first 3 numbers just backwards
Answer:
y - 1 = -4(x - 7)
General Formulas and Concepts:
<u>Algebra I</u>
Point-Slope Form: y - y₁ = m(x - x₁)
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
Slope <em>m</em> = -4
Point (7, 1)
<u>Step 2: Write Equation</u>
<em>Plug in variables into the general formula.</em>
y - 1 = -4(x - 7)
