The formula for the area of a circle is πr^2. Plug in the given radius for r. You now have π*2.2^2. Square the 2.2 first. 2.2^2 is 4.84. Now take that answer of 4.84 and multiply it by π or 3.14 as indicated in the directions for the problem. 4.84 * 3.14 = 15.1976
Now round that answer to the nearest tenth as the directions said to. 

Your answer should be:
15.2 ft.^2

500 = 12,375 * 0.7749^(n-1)<br><br> n = ?
aleksley [76]
Divide by 12375 and take the logarithm.
.. 500/12375 = 0.7749^(n -1)
.. log(4/99) = (n -1)*log(0.7749)
.. n = 1 +log(4/99)/log(0.7749)
.. n ≈ 13.583

What is the solution to <br> 2x -8 = 2(x - 4 ) ?<br><br> ALSO, explain how you solved it.
Genrish500 [490]
First, you gotta simplify. There’s really nothing to simplify so just take it out of the parenthesis.

2x-8=2x-4

Now turn the -8 into a +8. Add it on each side.

2x=2x+8

Now turn the 2x on the right into a negative. Do the same thing you did with the 8.
Now it’s:

0 = 8

That means there’s no solution.
Hope this helped :)
