PT 1
the circumference of a circle is always pi times the diameter. The diameter is 2 times the radius, because diameter is all the way across the circle, whereas radius is from the center of the circle to the edge. Anyways, if the radius is 6, multiply it by 2 and you get 12, so 3.14 times 12 is 37.68, which is the answer.
PT 2
diameter=9 cm. So, just do 9 times 3.14. (diameter times pi = circumference.)
(2*radius times pi = circumference.)
9 times 3.14 is 28.26

Answer:
angle 3 = 27 degrees
Step-by-step explanation:
<span>Assume that the number of full price tickets sold is x and the number of discount tickets sold is y since the total number of tickets sold is 240 then x+y=240 and since full price tickets sold were 180 more than the discount tickets x=y+180 </span>
Firstly, It says that the two triangles are similar .
The scale factor is 2 as 12 / 6 = 2
25 + 85 = 110
180 - 110 = 70.
70 degrees
