Radius given arc length and angle
WebThe radius of a circle can be calculated if we know the arc length and the sector area. A simple way is to substitute the given values in the formula, Area of sector = (Arc length × radius)/2. Let us understand this with an example. For example, if the arc length of a circle is given as 15 cm and the area of the sector is 225 cm 2. We know ... WebArc length is a fraction of circumference. Area of a sector is a fractions of the area of a circle. Both can be calculated using the angle at the centre and the diameter or radius.

WebFeb 3, 2024 · I'm in the process of writing a script for work but realized that I need to calculate the length of a circular arc intersected by two tangent lines, and when I try finding it I get lost in a mess of trig that seems to go nowhere. WebThe circumference can be found by the formula C = πd when we know the diameter and C = 2πr when we know the radius, as we do here. Plugging our radius of 3 into the formula, we get C = 6π meters or approximately 18.8495559 m. Now we multiply that by (or its decimal equivalent 0.2) to find our arc length, which is 3.769911 meters.
WebJun 28, 2024 · Let s be the length of the sagittus, a the length of the arc, r the radius, and θ the central angle. We are given a and s. We know a = r θ and s = r − r cos ( θ 2) so that a s = θ 1 − cos ( θ 2) A quick plot of f ( θ) = θ / ( 1 − cos ( θ / 2)) indicates that f is one-to-one on ( 0, π) so yes, s and a determine the angle.
