The function f(r) gives the circumference of a circle with radius r. It can be written in equation form as
f (r) = 27r or f (r) = 2 (3.14) r.
What is f(6)?
To find f(6), we need to substitute the value of r as 6 into the equation for f(r).
Using the equation f(r) = 27r:
f(6) = 27(6) = 162
Using the equation f(r) = 2(3.14)r:
f(6) = 2(3.14)(6) = 37.68
Therefore, f(6) is equal to 162 or 37.68, depending on which equation is used.
