Question

question 8 of 10

a cone is a polyhedron.

a. true
b. false

Explanation:

Define a polyhedron

A polyhedron is a three-dimensional solid whose faces are all flat polygons (such as triangles, quadrilaterals, etc.) meeting at straight edges.

Analyze the properties of a cone

A cone has a curved lateral surface and a circular base, which is not a polygon.

Evaluate the statement

Since a cone has curved surfaces and a non-polygonal base, it does not satisfy the definition of a polyhedron.

Answer:

• A. True
• B. False (Correct answer)
