Find the length of arc abc. express answer in terms of pi. pc=18in

Step-by-step explanation:

In the given figure we have given a circle in with radius PC = 18 inches

Also, the central angle made by arc AC or

Since the sum of angles at a point is  

Then , the central angle made by arc AC :-

The formula to find the arc length is given by :-

Then the length of arc ABC will be :-

Hence, the length of arc ABC =

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
