The height of the frustum of a cone is H. Derivate the formula for the volume of a cone using H, R, and r. Explain each step of solving process.

47 - 90 = 43

43 - 180 = x

x = 137

won't that be plagrisim thought?

step-by-step explanation:

80 the answer is 80

step-by-step explanation:

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
