THE function f (r) gives the circumference of a circle with radius r. It can be written in equation form as f(r) = 2 pi r or f(r) = 2 (3.14)r.

What is f (6)?
f(6) =

BTW I Put pi because I can't put the thing on here, sorry.

To calculate f(6), you can substitute 6 for r in the equation f(r) = 2πr.

f(6) = 2π(6)

Since you are using an approximation for pi as 3.14, you can plug in this value and simplify:

f(6) = 2(3.14)(6)

f(6) = 37.68

Therefore, f(6) is approximately equal to 37.68.
