x = 1, y = 4

Front

What is the formula for the circumference of a circle?

Back

C = \pi d or C = 2\pi r

Front

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

Back

Diameter = 2 × Radius

Front

Define a tangent line in relation to a circle.

Back

A tangent line is a straight line that touches the circle at exactly one point.

Front

What is the formula for the area of a circle?

Back

A = \pi r^2

Front

How do you find the length of an arc in a circle?

Back

Arc Length = (θ/360) × C, where θ is the angle in degrees and C is the circumference.
