Susan has a 12-inch board for constructing a wooden chair. The directions say to
use a board that is 29 centimeters long. Is her board long enough to cut?
(1 inch = 2.54 centimeters)

No it's not.

Step-by-step explanation:

Using the information you gave me(1 inch = 2.54 cm) in order for it to be enough you would need exactly 30.48 cm to construct the wooden chair. Hope this helps! :)

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
