To determine the volume of a cylinder and a cone, we use the following formulas:
Volume of a cylinder = πr^2h
Volume of a cone = 1/3Ï€r^2h
Let's compare the volumes of the cylinder and the cone:
For the cylinder:
Volume = π(10)^2(4) = 400π
For the cone:
Volume = 1/3Ï€(5)^2(12) = 100Ï€
Since the volume of the cylinder is greater than the volume of the cone, the cone with a radius of 5 and a height of 12 is not the correct answer. Let's check the other options:
For the cone with radius 15 and height 4:
Volume = 1/3Ï€(15)^2(4) = 300Ï€
The volume of this cone is also less than the volume of the cylinder, so it is not the correct answer.
For the cone with radius 15 and height 12:
Volume = 1/3Ï€(15)^2(12) = 900Ï€
The volume of this cone is greater than the volume of the cylinder, so this could be a valid solution.
For the cone with radius 5 and height 4:
Volume = 1/3Ï€(5)^2(4) = 100Ï€
This cone has the same volume as the cylinder, so it is also a valid solution.
Therefore, the correct answers are:
- Radius of the cone = 5; Height of the cone = 4
- Radius of the cone = 15; Height of the cone = 12
