Answer 13. = 12.9
Answer 14. = 15.1
Answer 15. = LM or PN (Any works pick one)
(13.) To find the circumference of a circle you have to use the formula
pi x d. The pi is 3.14 so you have 3.14 x 4.1 for the first question.
After multiplying, you should get 12.874 that is rounded off to 12.9.
(14.) To find the length of a arc, you have to use the formula 2pi(r)(0/360).
The r in this case is 4ft and the arc degrees measure 216. So you should get:
2(3.14)(4)(216/360) which equals 15.072 and rounded 15.1
(15.) A major arc is a arc of a circle that measures greater than or equal to (radians). When it saids "Name a major arc" This means there can be more than one and there is. The two major arcs are LM and PN. any will work.
He area of an equilateral triangle of side "s" is s^2*sqrt(3)/4. So the volume of the slices in your problem is
<span>(x - x^2)^2 * sqrt(3)/4. </span>
<span>Integrating from x = 0 to x = 1, we have </span>
<span>[(1/3)x^3 - (1/2)x^4 + (1/5)x^5]*sqrt(3)/4 </span>
<span>= (1/30)*sqrt(3)/4 = sqrt(3)/120 = about 0.0144. </span>
<span>Since this seems quite small, it makes sense to ask what the base area might be...integral from 0 to 1 of (x - x^2) dx = (1/2) - (1/3) = 1/6. Yes, OK, the max height of the triangles occurs where x - x^2 = 1/4, and most of the triangles are quite a bit shorter...

The answer would be add 13 because
12 + 13 would be 25, 25 + 13 would be 38. Hope this helps
Answer:
C) 2x
Step-by-step explanation:
The <em>Greatest</em> <em>Common Factor</em> <em>[</em><em>GCF</em><em>]</em><em> </em>means the LEAST DEGREE TERM possible, plus finding a common factor, in this case, between 6 and 2, which is 2. Together, the Greatest Common Factor is <em>2x</em><em>.</em>
