Answer:
530.66
Step-by-step explanation:
The way we find the area of the circle we use the radius of the circle for this one it's 13cm squared * pi or 3.14
For this circle we do 3.14 * 13^2
First we have to square 13: 13^2 = 169
Then we multiply 169 by 3.14: 3.14 * 169 = 530.66
Then we do to the nearest hundredth which is the same as the previous answer: 530.66
Answer: should be -1/ sqrt of 3. If it asks to rationalize it could be -sqrt of 3/3

Step-by-step explanation:
you round up 5 and make the 7 an 8
Answer:
x = 4/3
Step-by-step explanation:
15 - 5x = 6x + 3 - 2x
In this kind of equation, we try to seperate the x's and the numbers.
So we add 5x to both sides and subtract 3 from both sides to seperate these values
15 - 3 - 5x + 5x = 6x + 3 - 3 - 2x + 5x
=> 12 = 9x
=> 12/9 = x
=> 4/3 = x
=> x = 4/3
To check, we can plug this in.
15 - 5(4/3) = 6(4/3) + 3 - 2(4/3)
15 - 20/3 = 24/3 + 3 - 8/3
45/3 - 20/3 = 24/3 + 9/3 - 8/3
25/3 = 25/3
So our answer works.
I believe it is 2.5 if you need me to explain I can
