What is the circrumfrence of a circle with a diameter of 7 feet? Use 3.14 for pi

Step-by-step explanation:

if you take the diameter of a circle and put it around the circumference you will need to have 3 and a bit more (pi=3.14) of diameters to cover the whole circumference.

C = pi*d = 3.14 * 7 = 21.98 feet

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
