Find the measure of a circle
WebThe circumference of a circle is calculated using the formula: 2 x π x radius, where π is a mathematical constant, equal to about 3.14159. It was originally defined as the ratio of a circle's circumference to its diameter … WebSum of central angles in a circle = 360 º. 80º + 120º + x = 360º. Simplify. 200º + x = 360º. Subtract by 200 º on both sides. x = 160 º. Hence, the measure of the missing central angle is 160 degrees. Example 4.
