Evaluating a piece wise defined function

Given : If x ≠ -2 then f(x) =

As -5 ≠ -2 ⇒ f(-5) =

Given : if x = -2 then f(x) = -1

As x = -2 ⇒ f(-2) = -1

Given : If x ≠ -2 then f(x) =

As 2 ≠ -2 ⇒ f(2) =

i have no clue at all sorry

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
