There are 6 shaded squares out of 20 squares. That is the same as 30 out of 100. 30/100=30%

30%

Step-by-step explanation:

5*4 is 20.

So that your area.

6/20 converted to percentage: 30%

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

: )

it would open into a square depending on the type of envelope i’m not sure about the second part
