The given diagram represents a right circular cylinder with radius of base (r) 3 meter, and height (h) 11 meter,

The base of the cylinder is a circle, so its area (A) is given by,

Substitute the value,

Thus, the area of the base is approximately 28.3 sq. meters.
Now, consider that the height is directly given as 11 meters.
So the Blank 2 would contain the value 11 meter.
The volume (V) of a right circular cylinder whose base area (A) and height (h) is known, is given by the formula,

Substitute the values,

Thus, the volume of the given cylinder is approximately 310.9 cubic meters.
Therefore, the values in the three blanks are 28.3, 11, and 310.9, respectively.
