Question: 1 / 400

What does the term 'circumference' refer to in geometry?

Sum of lengths of sides

The distance around a circle

The term 'circumference' specifically refers to the distance around a circle. It is calculated using the formula \(C = 2\pi r\) or \(C = \pi d\), where \(r\) is the radius and \(d\) is the diameter of the circle. Understanding the concept of circumference is fundamental in geometry, particularly when dealing with circular shapes and their properties.

The other options relate to different geometric concepts: the sum of lengths of sides pertains to polygons, \(bh\) refers to the formula for the area of a rectangle where \(b\) is the base and \(h\) is the height, and the area of a trapezoid has its own specific formula. These concepts are distinct and do not apply to the definition of circumference.
