A circle has radius 10 centimeters. Suppose an arc on the circle has length `8\pi` centimeters. What is the measure of the central angle whose radii define the arc?

the answer is 24

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

what level of math? also i don't need to be paid if i can you.
