Angles and Segments in Circles

Front

What is the equation used to solve for x in the context of angles and segments in circles?

Back

The equation can be in the form of a linear equation derived from the properties of angles and segments, such as 6(2x + 6) = 128.

What is the relationship between the radius and the diameter of a circle?

Back

The diameter is twice the length of the radius.

Front

What is the formula for the circumference of a circle?

Back

C = 2πr, where r is the radius.

Front

What is the measure of a central angle in a circle?

Back

A central angle is an angle whose vertex is at the center of the circle and whose sides are radii.

Front

How do you find the area of a circle?

Back

The area A is given by the formula A = πr², where r is the radius.
