Domain= "number of minutes water has been added" and the set of all real numbers would be from 0-60

Range= "amount of water in the pond(in liters) and the set of all real numbers from 500-2000

I hope this helps

I'm terribly sorry if this is wrong  

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
