Answer:

D. 269.255 m³

Step-by-step explanation:

I think the question is asking for the volume of the cylinder.

The formula for the volume is written as:

V=πr²h

where r is the radius and h is the height.

using the given values,

r = 3.5 m

h = 7 m

V = πr²h

V = (3.14)(3.5)²(7)

V = 269.255 m³
