Arc and segment

Calculate the length of circular arc l, area of the circular arc S1 and area of circular segment S2. The circle's radius is 11, and the corresponding angle is 122π.

Correct answer:

l =  5.8
S1 =  31.7
S2 =  1.4

Step-by-step explanation:

l=122π11=5.8
S1=2122π112=31.7
S2=21112(122πsin122π)=1.4
