Question

the height of a cone is twice the radius of its base. what expression represents the volume of the cone, in cubic units? o 2/3πx^3 o 4/3πx^2 o 2πx^3 o 4πx^3

Answer 1

V=2/3πx^3

Explanation:

Volume of Cone: V=r^2πh/3

h=2r --> height is twice the radius

V=r^2π(2r)/3

V=r*r^2π(2)/3

V=2/3πr^3

V=2/3πx^3
