M is the midpoint of PQ. The diameter of circle O is 15 in. and RM = 3 in.

PM=6 inches

PQ=12 inches

Step-by-step explanation:

-The product of the segments of chords that intersect within a circle are always equal.

Given that PM=MQ and RS=15(MS=15-3=12):

Hence, the length PM is 6 inches and PQ is 12 inches

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
