(2.1)-2

(2.5) (-3.25)

-10 (3.2) (-7.3)

Column B

790 10

(7.9) 10

-67 7

(0.1) -60

(2.1)-2

(-8.4) 12

(2.5) (-3.25)

-52134

-10 (3.2) (-7.3)

5 (-1.6) (-29.2)

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

i would say b) is your answer
