What is circumference? Please select all that apply:

A) distance around the circle
B) the space inside the circle
C) To find the circumference C of a circle if you know the diameter d is to multiply pi by the diameter
D) To find the circumference if you know the radius, replace d with 2r in the formula
E) the formula for circumference is C=pi + r

A, C and D are correct.

\

Step-by-step explanation:

A is correct.

B is false; that space is the "area" of the circle.

C is true.  C = πd

D is true.  C = 2πr

E is false.  Way off.

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
