Arc Length
We are given a circle with a central angle of θ=54° and radius r=19 units.
The formula to calculate the length of an arc is:
L = θr
Where θ must be expressed in radians.
We must express the angle in radians:
θ = 54 * π / 180 = 3π/10
Now calculate the arc length:
L = 3π/10*19 = 4.96
The length of arc EG is 4.96 units
