Circle and angle

What is the length of the arc of a circle with radius r = 207 mm with cental angle 5.33 rad?

Result

d =  1103.3 mm
S =  114192.6 mm2

Solution:

d=5.33⋅207=1103.3 mmd = 5.33 \cdot 207 = 1103.3 \ \text{mm}
S=20722⋅5.33=114192.6 mm2S = \dfrac{ 207^2}{2} \cdot 5.33 = 114192.6 \ \text{mm}^2
