Step-by-step explanation:
The volume of a cone can be derived by writing an expression that represents the volume of one cone within the cylinder.
the expression for the volume of a cylinder is

the volume of a cone is a part of the volume of a cylinder

Hence the volume of a cone can be derived by dividing the volume of a cylinder by 3
I assume you're asking to convert 114₅ to base 10. We have
114₅ = 1•5² + 1•5¹ + 4•5⁰
114₅ = 25 + 5 + 4
114₅ = 34
D, all apply
You can cut all in half and they will be equal
