surface area = 2*(pi)*r*h+2*(pi)*r^2
using 3.14 as pi
2*3.14*4*20 + 2*3.14*4^2 = 602.88m^2
Answer:60.58
Step-by-step explanation:add the first numbers 64.67 take that from 125.25 and u got 60.58
Answer:
2/3
Step-by-step explanation:
To get the slope, you do (y2-y1)/(x2-x1).
You can also remember it as rise/run, as it is the change in y/change in x.
You can make either coordinate 1 or 2, just keep it consistent with the rest of the problem.
For this, I chose (-5, -7) to be 2, and (4, -1) to be 1.
Following the formula for slope, (y2-y1)/(x2-x1), you put the values in: (-7-{-1})/(-5-4).
-7 minus -1 is -6 and -5 minus 4 is -9.
Thus you get -6/-9. Don’t forget to simplify! A negaive divided by a negative is positive, and both 6 and 9 can be divided by 3. 3 goes into 6 TWO times and into 9 THREE times.
So, you get a positive fraction, 2/3.
Hope this helped.
Answer:For B I have 42 minutes.
Step-by-step explanation:
First 4 people x 8 minutes per person = 32.
Plus the additional 10 minutes = 42 minutes
