Well, you take 0.199 find the hundredths place, which is the 9 to the left in this example, and decide whether the number to the right of the nine is more than 5, which it is, so we round the 9 up. However, we can't just make it 10 hundredths, so we have to simplify it to 1 tenth and add it onto the tenths place to make 0.20.
Assuming that you mean the FIFTH power then
7^5=7*7*7*7*7=16,807

Step-by-step explanation:
Answer:
Area = πr², where "r" is some distance "y" and/or the function "(1/6)x"; depending on the situation
Step-by-step explanation:
If I'm picturing this correctly, you'll have conical shape after revolving the function about the x-axis. If you took some generic slice and wanted to find the area of the resulting cross-section, then you would have a circle whose radius is some arbitrary value of the line that matches the slice.
For example:
y = (1/6)x right?
If you took a slice at x = 2, then the radius of the resulting cross-sectional circle would be equal to y = (1/6)•2 =1/3.
From here you just plug it into the area of a circle, πr², to get an area of π/3.
Except with an integral you need to take all the points on the interval, so the radius comes out to be the function itself.
Assuming your integral is in terms of dx, r=y. But in order to integrate in terms of dx you must replace "y" with its function (1/6)x. So ultimately r=(1/6)x and Area = π(1/6)x.
