C.If the measure of is 1 radian, then the arc length is r.. D.The ratio of arc length to r is always equal to 1.

From my research, the figure related to this image has a circle with a marked sector. The sector's radius is labeled r, and the angle labeled theta. Among the choices, the correct ones are: A. "If the ratio of the arc length to r is 1, then the measure of is 1 radian" and C. "If the measure of is 1 radian, then the arc length is r"

Based on the scenario above, the true statement about the figure are:

"If the ratio of the arc length to r is 1, then the measure of is 1 radian".
"If the measure of is 1 radian, then the arc length is r".

What is the ratio of arc length?

Note that in circle of radius r, the ratio of the arc length ℓ to the circumference is known to be the same as the ratio of the angle θ that has been held by the arc.

Therefore, Based on the scenario above, the true statement about the figure are:

"If the ratio of the arc length to r is 1, then the measure of is 1 radian".
"If the measure of is 1 radian, then the arc length is r".
