Answer:
26 cm^3
Step-by-step explanation:
volume of cylinder = (pi)r^2h
volume of cone = (1/3)(pi)r^2h
Since (pi)r^2h = volume of cylinder, then you get
volume of cone = (1/3)(volume of cylinder) = (volume of cylinder)/3
The difference between the volume of a cylinder and the volume of a cone is that a cone with the same radius and height has 1/3 the volume of the cylinder.
If you know the volume of a cylinder, then the volume of a cone with the same radius and height is 1/3 the volume of the cylinder, or simply, divide the volume of the cylinder by 3.
volume of cylinder = 78 cm^3
volume of cone = (78 cm^3)/3 = 26 cm^3
His answer was wrong. The correct answer would be 129,000
Explain: 500 rounded to the nearest thousand would be 1000
But 499 rounded to the nearest thousand would not become 1000
