Hi, to answer this question we have to use the next formulas:

Volume of a cylinder: area of the base x height

Volume of a cone: 1/3 x area of the base x height

So, we can say that

Volume of a cone = 1/3 x volume of a cylinder  

Replacing with the value given:

Volume of a cone = 1/3 ( 102) =34 cm3
