How do you find circumference physics
WebThen find the arc length using the relevant formula. Example: Calculate the arc length of a curve with sector area 25 square units and the central angle as 2 radians. We have, Sector area = 25 units. Central angle = 2 radians. Step 1: Sector area = 25 ⇒ (1/2) r 2 (2) = 25; Step 2: This gives r 2 = 25. By taking square root on both sides, r = 5. WebCircumference = π × diameter = 2 π × radius. In geometry, the circumference (from Latin circumferens, meaning "carrying around") is the perimeter of a circle or ellipse. [1] That is, …
