Ellis is painting the wooden fenceposts in his yard. they are each 7 feet tall and have a diameter of 1 foot. there are 11 fenceposts in all. how much paint will ellis need to paint all the surfaces of the 11 fenceposts? use 3.14 for π, and round your answer to the nearest hundredth.

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

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.

step-by-step explanation:

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
