Good luck

Step-by-step explanation:

C = 78.54

A = 490.87

Step-by-step explanation:

1. Circumference Formula

C = 2πr (r=d/2=12.5)

C = 2π12.5

C ≈ 78.54

In terms of pi:

25π

2. Area of circle

A = πr^2

A = π12.5^2

A ≈ 490.87

In terms of pi

156.25π or 625π/4

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.
