Question

which of the following is a counterexample for this conditional statement? if a three - dimensional solid has a circular base, then it is a cone. a cone a pyramid a cylinder a cube

Explanation:

Step1: Analyze the conditional statement

The statement claims that if a 3 - D solid has a circular base, it's a cone. A counter - example must have a circular base but not be a cone.

Step2: Check each option

• a cone: It has a circular base and is a cone. Not a counter - example.
• a pyramid: Usually has a polygonal (non - circular) base. Not a counter - example.
• a cylinder: Has circular bases but is not a cone. A counter - example.
• a cube: Has square (non - circular) bases. Not a counter - example.

Answer:

a cylinder
