The figure represents a section of a circle. What is the angle theta ? What is the arc length s?

Solution

solution-: A) Here we have ( 3, 8)

tan theta = 8/3

theta= arc (8/3) =69.4 degrees

B ) To find arc we will apply formula radius = 8.5

Length = 2*pi*r theta/360=2*(3.14)*(8.5)(69.4)/360

=3704.57/360

=10.3 answer
