Answer: option A
Step-by-step explanation:
The volume of a cylinder can be calculated with the formula:

Where r is the radius and h is the height of the cylinder.
The radius is diameter divided by 2, then:

Substitute the radius into the formula. Then you get the following equation that can be used to find V, the volume of the cylinder:

There is a square and a triangle
the area of a square is
A = b * h
A = 2*2
A = 4
the area of the triangle is
A = (b*h)/2
A = (2 *2)/2
A = 4/2
A = 2
Now we add them up to find the total area
4 + 2 = 6
The shape has an area of 6 units^2
