Which expression represents the volume of this solid ?

Answer:
The answer is option 5.
Step-by-step explanation:
The formula is V = 1/3×π×r²×h where r represnt radius and h is height. Given that the diameter of cone is 8 inches so the radius is 4 inches then substitute the value into the formula :
[tex]v = \frac{1}{3} \times \pi \times {r}^{2} \times h[/tex]
Let r = 4,
Let h = 12,
[tex]v = \frac{1}{3} \times \pi \times {4}^{2} \times 12[/tex]
[tex]v = \frac{( {4}^{2}\pi)12 }{3} [/tex]
