Acone has a diameter of 8 units and a height of 8 units. its radius is units, and its volume is cubic units. a cylinder with the same height and radius as the cone will have a volume of cubic units. if a sphere has the same radius as the cylinder, its volume is the volume of the cylinder.

try this solution:

1) volume of the cylinder is: v(cyl)=π*r²(cyl)*h(cyl)=16*8π=128π (units³);

2) volume of the sphere is: v(sph)=4π/3 *r³(sph)=64*4π/3=256π/3 (units³);

3) the volume of the sphere is the volume of the cylinder:

v(sph)/v(cyl)=128/(256*3); ⇒ v(sph)=2/3 *v(cyl).

answer: 2/3

answer: x=3 and y=4
