In your answer, give the volume of the cone rounded to the nearest tenth, and then
explain how you calculated it. (Note: type out all of your work AND type out your
explanation for FULL credit.)
Answers
Answer:
39.5 in^3
Step-by-step explanation:
lol someone had the same question
The formula for a cone is (pi)(r^2)(h/3)
Since we have to use 3.14 for pi, we plug 3.14 in for pi:
(3.14)(r^2)(h/3)
The radius is 2 and the height is 8, so we plug in those numbers:
(3.14)(2^2)(8/3)
Simplify:
(3.14)(4)(2.666...)
Multiply:
(12.56)(2.666...) -> 39.49333...
Finally, we round 39.49333... to the tenths place:
39.5

how do i solve this?
Answers
There’s a few ways to approach this. You just need to figure out which equations are on that graph. I’d start by identifying the equations for the lines. Remember y=mx+b where mx is the slope and b is the y-intercept. Let’s start with the y-intercepts. They’re labeled for you. One is (0,4) and the other is (0,-4). So we have y=mx+4 and y=mx-4. Next, we need to find the slope. You can count the boxes to do that. Find a neat spot where the line crosses a corner (the y-intercept is often a good place to start) and make a sort of triangle using the line as one side. Count the boxes it takes to get up and over to the next intersection at a corner. The line that crosses at (0,4) goes up (rise) one and over (run) one equally. Rise over run, 1/1x. That can be simplified to just x. So one line is y=x+4. The other line goes down two for every one box it goes over. Remember that when it goes down, it’s negative. So that’s -2/1x, or just -2x. The equation is y=-2x-4. Both of those answers are only present in option J.

Determining the area of a trapezium?The trapezium is a 2 -dimensional plane shape with the area calculated as shown below:
The formula for calculating the area of a trapezoid is expressed as:
Area = 0.5(a + b)h
Given the following parameters
a = 500 ftb = 900ft
height h = 800ft
Substitute the given parameters
Area = 1/2 (500 + 900) * 800
Area = 1/2 (1400) * 800
Area = 560000 square feet
Since 1 acre is equivalent to 43560 square feet, hence the total acre required is expressed as:
Total acre = 560000/43560
Total acre = 12.856 acres
Also since there are 37000 plants per hectare, the total corn plan required is 475,665.75 corn plants

Given that cos(theta) = 8/17 and that theta lies in Quadrant IV, what is the exact value of sin 2(theta)?
Answers
Answer: [tex]-\frac{240}{289}[/tex]
=========================================================
Explanation:
Use the pythagorean trig identity [tex]\sin^2(\theta)+\cos^2(\theta) = 1[/tex] and plug in the fact that [tex]\cos(\theta) = \frac{8}{17}\\\\[/tex]
Isolating sine leads to [tex]\sin(\theta) = -\frac{15}{17}\\\\[/tex]. I'm skipping the steps here, but let me know if you need to see them.
The result is negative because we're in quadrant 4, when y < 0 so it's when sine is negative.
Therefore,
[tex]\sin(2\theta) = 2\sin(\theta)\cos(\theta)\\\\\sin(2\theta) = 2*\left(-\frac{15}{17}\right)*\left(\frac{8}{17}\right)\\\\\sin(2\theta) = -\frac{240}{289}\\\\[/tex]
