Answer:
Option B. 1077.02 cubic units
Step-by-step explanation:
As we know the formula of cone is [tex]V = \frac{1}{3}\pi r^{2}h[/tex]
In the given question given dimensions are h = 21 units and r = 7 units.
Therefore we can calculate the volume of the cone with the given dimensions.
[tex]V = \frac{1}{3}\pi(7)^{2}(21)[/tex]
[tex]V=\frac{1}{3}(3.14)(49)(21)[/tex]
V = 3.14×49×7 = 1077.02 cubic unit
So the volume of the given cone is 1077.02 cubic units
