In a circle with a radius of 8 ft, an arc is intercepted by a central angle of 3π4 radians.

what is the length of the arc?

The arc length  is, 18.84 ft.

Step-by-step explanation:

Length of an arc is given by:

             .....[1]

where r is the radius of the circle and is the angle in radian.

As per the statement:

In a circle with a radius of 21 5/8 yd, an arc is intercepted by a central angle of radians

⇒r = 8 ft

and radian

Substitute these values in [1] we have;

ft.

therefore, the arc length  is, 18.84 ft.
