First we need to find the radius. Using Pythagorean theorem we can find the radius which is the distance between the center and any point along the circle:
r=((5-1)^2+(2-2)^2)^(1/2)
r=(4^2-0^2)^(1/2)
r=4 units.
Circumference=2pr so our circumference is 8p units^2
Approximately 25.13 u^2
Answer:
it is .8333333333 and more 3's forever
Step-by-step explanation:
2 because there are 4 numbers of edges and 4 vertices
x < -9 or x > 7
x + 1 < -8
x < -9
x + 1 > 8
x > 7
... when the inequality sign is facing the x, x is GREATER and it resembles an OR statement. I personally like to think of it as: greater than (greatOR than) = or statement; less than (less thAND) = and statement.
