Volume of Hemisphere = 2/3 * Pi * (radius)^3 Volume of Cone = 1/3 * Pi * (radius)^2 * height where Pi = 22/7 (approx)
27 cm3
The formula for the volume of a cone is V = (1/3)πr^2h, where r is the radius and h is the height. Plugging in the values given, the volume of the cone would be V = (1/3)π(3cm)^2(6cm) = (1/3)π(9cm^2)(6cm) = 54π cm^3. Therefore, the volume of the cone with a radius of 3cm and height of 6cm is 54π cubic centimeters.
