Find the circumference of each circle. use 3.14 or 22/7 for π.
a button with a radius of 21 millimeters

C =132 mm

Step-by-step explanation:

The circumference is given by

C = 2*pi*r

We know pi = 22/7 and r = 21

C = 2 * 22/7 *21

C = 44/7 *21

C =132 mm

step-by-step explanation:

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
