Which of these fractions are greater than 11/20 ? A 3/4 B 3/10 C 4/5 D 1/2

a,c

Step-by-step explanation:

convert them all into a denominator of 20

3/4 = 15/20

3/10 = 6/20

4/5 = 16/20

1/2 = 10/20

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
