Find the length of arc ac. express your answer in terms of pi.

Given that: AB = 12 ft.

From the given figure we have;

diameter = AB = 12 ft.

ft.

Supplementary angles states that the two adjacent angles are sum up to 180 degree.

and are supplementary angles.

by definition of supplementary angles;

Subtract   from both sides we get;

To find the length of arc AC;

Formula for length(L) of arc is;

substitute the given values; we have;

ft

Therefore, length of arc AC is, ft

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
