Answer:
The answer is B.
Step-by-step explanation:
Given that the formula of volume of cylinder is, v = π×r²×h where r represents radius and h is height of the cylinder. So you have to substitute the value of r and h into the formula :
[tex]v = \pi \times {r}^{2} \times h[/tex]
Let r be 7 units,
Let h be 4 units,
[tex]v = \pi \times {7}^{2} \times 4[/tex]
[tex]v = \pi \times 49 \times 4[/tex]
[tex]v = \pi \times 196[/tex]
[tex]v = 196\pi \: {units}^{3} [/tex]
