For the 3 circles, in increasing order of the radius, we have:
- L₁ = 2.09
- L₂ = 4.18
- L₃ = 6.28
How to get the arc lengths of the circles?
For a circle of radius R, the arc defined by an angle θ (in degrees) is given by:
L = (θ/360°)*2pi*R
Where pi = 3.14
In this case, we have 3 circles of different radius, and θ = 60°, then we have:
circle 1:
radius = 1 unit, then:
L₁ = (60°/180°)*2*3.14*1 = 2.09
circle 2:
radius = 2 units, then:
L₂ = (60°/180°)*2*3.14*2 = 4.18
circle 3:
radius = 3 units, then:
L₃ = (60°/180°)*2*3.14*3 = 6.28
