प्रश्न
The volume of the largest right circular cone that can be fitted in a cube whose edge is 2r equals to the volume of a hemisphere of radius r.
पर्याय
True
False
उत्तर
This statement is True.
Explanation:
Given, edge of cube = 2r, then height of cube becomes h = 2r.
Volume of a cone = `1/3 pir^2h = 1/3 pir^2(2r) = 2/3 pir^3`
Volume of a hemisphere = `2/3 pir^3`
Hence, the volume of a cone is equal to the volume of a hemisphere.
