DilationsDiameter: d = 2rVolume of a Cone: [tex]V= \frac{1}{3} \pi r^2h[/tex]Step-by-step explanation:
Step 1: Define
Height h = 8
Diameter d = 6
Base b = 5.4 (not needed in calculations)
Step 2: Find radius r
Substitute: 6 = 2rIsolate r: 3 = rRewrite: r = 3Step 3: Find V of Normal Dimensions
Substitute: [tex]V= \frac{1}{3} \pi (3)^2(8)[/tex]Exponents: [tex]V= \frac{1}{3} \pi (9)(8)[/tex]Multiply: [tex]V= 24 \pi[/tex]Evaluate: [tex]V \approx 75.3982[/tex]Step 4: Find Dilations
Scale Factor: 2
Define radius: r = 3Dilate: r' = 3(2)Multiply: r' = 6Define height: h = 8Dilate: h' = 8(2)Multiply: h' = 16Step 5: Find V of Dilated Dimensions
Substitute: [tex]V= \frac{1}{3} \pi (6)^2(16)[/tex]Exponents: [tex]V= \frac{1}{3} \pi (36)(16)[/tex]Multiply: [tex]V= 192 \pi[/tex]Evaluate: [tex]V \approx 603.186[/tex]What is 20% less than 18.5?

In the slope-intercept form, which variable
represents the slope/measure of change?
Answers
Step-by-step explanation:
Hey there!
We know that the slope intercept is; y = mx+b.
Where "m" represents the slope. And "b" represents the y-intercept.
Example:
If the question is as; y = 3x +8
Then your slope of the slope intercept form is "3" where as "8" is y-intercept.
So, the variable"m" represents the slope.
Hope it helps...
