A 216 degrees sector of a circle of radius 5 cm is folded to form a cone. Find: (a) the radius of the base of the cone and (b) its vertical angle.

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
