Mis the midpoint of pq. the diameter of a circle o is 13 in. and rm = 4 in.

Part a)

Part b)

Step-by-step explanation:

step 1

we know that

The diameter of the circle divide the circle into two equal parts

so

PM=MQ

Applying the Intersecting Chord Theorem (When two chords intersect each other inside a circle, the products of their segments are equal)

we have

substitute

step 2

Find the value of PQ

we know that

so

we have

substitute

- 70

this is the answer for you hope it
