Formula for the circumference of a circle:
C = 2πr (C = circumference π(pi) = 3.14..... r = radius)
You know:
r = 9 cm
π = 3.14 So substitute/plug it into the equation
C = 2πr
C = 2(3.14)(9)
C = 56.52 cm
Answer:
B. 
Step-by-step explanation:
Answer:
5.7
Step-by-step explanation:
Creating the point into a triangle, both sides a 4.
As the Pythagorean theorem goes, a^2+b^2=c^2
4^2+4^2=
16+16=
32
The square root of 32 is about 5.7
The distance between the points is about 5.7 units
