Circumference of a circle with angle
WebAnd it works out for every ratio. a tenth of the circumference will have a tenth of the angle. 1/pi of the circumference will have 1/pi of the angle. Now, for this, the circumference is 2pir by defenition And the angle is 2 radians. Of course the full angle all the way around is 2pi. So if we call the arc length S that gives us S/ (2pir) = 2/2pi. WebExample 1: If the radius of a circle is 7 units, then the circumference of the circle will be. 2 × π × 7 = 2 × 3.14159 × 7. = 43.98 units. Example 2: Suppose that the diameter of the circle is 12 feet. Then, we can use the …
