The formula for this is

. If the diameter is 8 the radius is 4, so filling in accordingly we have

and

which is

and when you multiply in 3.14 you get that A = 401.92 or B above.
6, I guess. 1 red and 6 green, 2 red and 5 green. 3 red and 4 green, 2 green and 5 red, 1 green and 6 red, 3 green and 4 red,
A straight line is 180 degrees and 144 is on a straight line. So, 180-144 which is 36. So, now we know 2 angles and the Degrees of a triangle is 180 degrees.
36+76+d= 180 D= 68
Answer:
x= -1
Step-by-step explanation:
6-3x=5x-10x+4
6-3x=-5x+4
-4 -4
2-3x=-5x
+3x +3x
2=-2
2/-2=-2x/-2
-1=x
