Question

Find the length of arc YXZ. A. s=3 B. s= 60 C. s= 75 D. s= 236

Answer 1

Answer:

C. s= 75

Step-by-step explanation:

One radian is the angle subtended by an arc length equal to the radius of the circle.

∅=s/r where s is the arc length ∅ the angle and r the radius of the circle.

Thus s=∅×r

In the circle provided arc s subtends and angle of 5 radians.

s= 5 radians× 15

=75

Answer 2

B. S=60 , dont know for sure
