For a long time, mathematicians weren't sure that asymmetric encryption was possible. Fortunately, cryptographers discovered the necessary mathematical innovation in the 1970s and invented public key encryption. If public key encryption was never invented, what wouldn't be possible today?

a

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

6 x 4 = 24
