To find the volume of the cone in the picture where S equals 13CEM and R equals 5CM

Volume = (1/3)πR2H

Volume = (1/3)π(5CM)2(13CM)

Volume = (1/3)π(25CM2)(13CM)

Volume = 325πCM3

Just so much gibberish by the robot

See my answer to Amy two posts above this one, same type of
problem, same type of solution.
