Answer:
F. None of the above
Explanation:
A cone is produced by rotating the shape about line m.
The height of the cone will be 0.5 because it's perpendicular to the base.
Since the height is 0.5, the answer is not A or B.
The circular base is formed by the line split into two "1"s. Each "1" is the radius, together, the diameter of the base.
Since r = 1, the answer is not C.
Since d = 2r = 2(1) = 2, the answer is not D.
∴ The answer is none of the above, F.
