Lesson 6.2b Circles

The definition of a circle is

• set of all points in a plain that are the same distance from a point called the center

• the distance around a share

• a large figure

• a pizza, orange, plum, or watermelon

The definition of radius is

• distance from one point to another point

• distance around the circle

• distance from the center to any point on the circle

• distance across the circle through the center

The definition of circumference is

• distance from the center of any point on the circle

• distance from one point to another

• distance around the circle

• distance from the center of any point on the circle

what is the formula for finding diameter

• r = 2 d

• d = 2 r

• a = m c²

• c = π 2 r
