Below are three circles.
The circumference and diameter of each circle have been approximately measured.
Circle 1:
Circle 2:
Circle 3:
Circumference: 17.281 units Circumference: 19.633 units Circumference: 47.139 units
Diameter: 5.5 units Diameter: 6.25 units Diameter: 15 units

(b) Let C represent the circumference of any circle and d represent the diameter.
Using the fact that is approximately 3.14, which formula seems reasonable?

for any of you who need the translation here it is

step-by-step explanation:

find the angular size of the equatorial radius of the earth, if the horizontal parallax of the sun

this is answer of 144 cubic meters

b

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.
