<h3>
Answer: Choice C) Construct a tangent from an external point</h3>
=================================
Explanation:
The idea is that you have some circle and a point outside the circle. This point is labeled M. The center of the circle is point O. A perpendicular bisector is constructed to segment OM, after which a compass is used to draw the arc marking to form point G. Line MG is perpendicular to the radius segment OG. Therefore, line MG is tangent to the circle and it goes through point M.
To get the answer you have to fill in the 14 for r because that is the radius. Then multiply 14 by it self to get 196 then multiply that by pie to get your answer of 615.75216.
So the answer is 615.75216
B. 12n - (6n+3) = 21
D. 4(n+6) - 3n = 28
Answer:
Step-by-step explanation:
You start off with 82 on Friday, then subtract 2 to find the temperature of Saturday, which is then 80.
Once you have Saturday's temperature, you add 5 to it, which is 85.
Now you know it is 85 F on Sunday. EQUATION:(82- 2)+5=85
