The ratio of the circumference of a circle to its diameter is A
always \piπ:1.

B
equal to the area of the circle.

C
dependent on the length of the radius.

D
different depending on the size of the circle.

always piπ:1. "A"

Step-by-step explanation:

circumference of a circle= 2πr

diameter of a circle=2r

ratio of circumference to radius=2πr/2r

=π/1 or π:1

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
