Match each division problem with its representation of equal groups. 18 + 6 = 3
There are 5 equal groups of 3
45-5=9
There are 4 equal groups of 2
15 - 3 = 5
There are 9 equal groups of 5.
8 - 4 = 2
There are 3 equal groups of 6

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
