Question

What is the length of arc S shown below? Enter an exact expression in units. The angle in the figure is a central angle in radians.

Answer 1

Answer:

The length of arc S = 47.1

Step-by-step explanation:

The radius of the circle = 10

The central angle of the arc = 3$\frac{\pi }{2}$

By formula, S = rΘ

where S is the lenth of the arc

r is the radius of the circle

Θ is the central angle of the arc

substituting the values in the formula, we get

S = rΘ = 10 (3$\frac{\pi }{2}$) = 15$\pi$ = 47.1

Answer 2

Answer:

15pi
