Explanation:
According to the problem, calculation of given data are as follows,
Volume of cylindrical vase =
![63cm^(3)](https://img.qammunity.org/2022/formulas/mathematics/high-school/bl3tfahdxl8r8p56qw22sm4q0fngnyyd5y.png)
As, Cone has same height and radius as cylinder, than we can calculate volume of cone by using following formula,
Volume of cone =
× Volume of cylindrical vase
By putting the value, we get
Volume of cone =
× 63
Volume of cone =
![21cm^(3)](https://img.qammunity.org/2022/formulas/mathematics/high-school/rrbgxyqtp33elod4q9ie7pg02gxci517hc.png)
