Answer:
f(r) = 2πr
Step-by-step explanation:
You know the formula for circumference in terms of radius is ...
C = 2πr
You are being asked to write this as a function named "f". That will be ...
f(r) = 2πr
Answer:
[tex]f(r)=2\pi r[/tex]
Step-by-step explanation:
The formula for circumference of a circle is
[tex]C=2\pi r[/tex]
where,
C represent the circumference of the circle.
r represent the radius of the circle.
It is the function f determines the circumference of the circle in cm, C C, given its radius length in cm, r.
So, the circumference of the circle is defined by the function
[tex]f(r)=2\pi r[/tex]
Therefore the required formula for function f is [tex]f(r)=2\pi r[/tex].
