Based on the calculations, the measure of this angle in radian is equal to 0.75 radian.
How to calculate the length of the arc?
In Geometry, the length of an arc formed by a circle can be calculated by using this formula:
S = rθ
Where:
- r is the radius of a circle.
- θ is the angle measured in radians.
- S is the length of an arc.
Making θ the subject of formula, we have:
θ = r/S
Let S = 4 inches and r = 3, we have:
θ = 3/4
θ = 0.75 radian.
