Question

What is a great circle?

A. A circle on a sphere made by performing a plane cut anywhere on the sphere
B. A circle on a sphere that has the same radius and center as the sphere itself
C. A circle on a sphere that doesn't pass through the sphere's center
D. Another name for a sphere

Answer 1

B) A circle on a sphere that has the same radius and center as the sphere itself

Step-by-step explanation: I took the test

Answer 2

B

Explanation:

It's not D. A sphere is a sphere. A billiard ball is a billiard ball. Both are spheres. No other name applies to the sphere.

It is not C. That might be true if you are talking about a circumference.

The exact definition is B. B is the answer.

A is not true. The cut must go through the center as B suggests.
