Isabella’s error is Isabella should have divided the product of 12π and 9 by 3 to get V = 12π(9)/3 option fourth is correct.
It is defined as a three-dimensional shape in which the base is a circular shape and the diameter of the circle decreases as we move from the circular base to the vertex.
[tex]\rm V=\pi r^2\dfrac{h}{3}[/tex]
Isabella equation:
[tex]\rm V = \dfrac{1}{3}(12)^2(9)\pi[/tex]
The area of the base = 12π square cm
[tex]\rm V = \dfrac{12\pi (9 )}{3}[/tex]
Thus, Isabella’s error is Isabella should have divided the product of 12π and 9 by 3 to get V = 12π(9)/3 option fourth is correct.
