V≈254.47
Which rounded to the nearest tenths place, is 254.5
The equation to find the volume of a cylinder is V=πr^2h, so if we input 3 into where r is, and if we input 9 in the place of h, we get V=π(3^2)9
If we solve the exponent, now it’s V=(π9)9. So now we multiply pi by 9, then that by 9, and you get 254.47
Ok so standard form is a bit tricky, but I’ll help explain
Here’s and example:
If you have 2x+5y=10 here is how you would solve it
First you divide the x value by what the number is equal to (in our example, 10), and then we get 10/2 is 5. So now we know that
x is equal to five
Keep that in mind. Now we just have to do the same thing for the y value. 5/10 is 2, so you know that
y is equal to two
NOW you put those two together, and graph on the intercepts (the positions on the y and x axis where the lines intercept)
You would put a line on the x axis at 5, and on the y axis at 2
If you have any questions, you can ask
That's A because the segmento B represents the "time" he stayed at the Red light
