Concept 44: I can determine the circumference of a circle and use the circumference of a circle to find its diameter and radius. 3. Find the circumference of the circle shown.

Step-by-step explanation: to find circumference, u do 2*pi*radius or pi times diameter

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

add them

idk you did not give the options or numbers so you cant solve it
