So, we have:



I am pretty sure your answer is going to be 243
I hope this helps, and good luck!!
So the question ask to determine how long that the wooden artifact found in an ancient tombs and contains 70% of the carbon-14 was made, and base on the fact and the given data about the said artifact, the possible answer would be that the the artifact is 2948 years old. I hope you are satisfied with my answer
formula is pi*r*(r+sqaureroot(h^2+r^2)
plug in the numbers and the calculated area is 1507.96
but since you cant use fraction or decimals
the answer should be 480PI
Answer:

Explanation:
Slope-intercept form formula:

For this formula we need the slope to find the slope use the slope formula:

Plug in the two points (1,-3) and (3,1)

=2
the slope is 2
Now use the slope-interpect formula and plug in the slope (m)

plug in one point I'll use (3,1)

1 = 6 +b
1-6=6-6+b
-5 = b
The equation would be:
