Question

question 4 of 10

which of the following choices describe the bases of a cylinder?

check all that apply.

a. discs
b. polyhedrons
c. congruent
d. parallel

Explanation:

Analyze the definition of a cylinder

A cylinder is a three-dimensional solid geometric figure with two parallel, congruent circular bases (or discs) connected by a curved surface.

Evaluate each option against the definition

• A. Discs: Correct. The bases of a cylinder are circular regions, which are mathematically described as discs.
• B. Polyhedrons: Incorrect. A polyhedron is a solid with flat polygonal faces. A cylinder has a curved surface and circular bases, so it is not a polyhedron.
• C. Congruent: Correct. The two circular bases of a cylinder must be identical in size and shape.
• D. Parallel: Correct. The two bases of a cylinder lie in parallel planes.

Answer:

• (A) Discs (Correct answer)
• (B) Polyhedrons
• (C) Congruent (Correct answer)
• (D) Parallel (Correct answer)
