P = 76 feet, A = 338 square feet
O P = 58 feet, A = 338 square feet
O P = 76 feet, A = 330 square feet
P = 91 feet, A = 390 square feet
What is the perimeter and area?

astronomers is your final answer! : )

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 believe it's a.

i'm not sure on this one, most likely correct.

the answer is c hope this
