Volume of a cylinder is 330 cm3. The volume of the cone having same radius and height as that of the given cylinder is:
पर्याय
330 cm3
165 cm3
110 cm3
220 cm3
उत्तर
110 cm3
Explanation:
Volume of a cylinder is 330 cm3.
Volume of a cylinder = πr2h
Volume of the cone = `1/3 πr^2h`
Volume of the cone = `1/3` × Volume of a cylinder
Volume of the cone = `1/3` × 330 cm3
Volume of the cone = 110 cm3
