Find the arc length of the shaded region. Multiply through by #(3.14) Round solution to
tenth place. Ex. 1.2
90°

Given:

The radius of the circle is 12 units.

The central angle of the shaded region is 90°

We need to determine the arc length of the shaded region.

Arc length:

The arc length of the shaded region can be determined using the formula,

substituting and r = 12, we get;

Multiplying the terms, we have;

Dividing, we get;

Rounding off to the nearest tenth, we get;

Thus, the arc length of the shaded region is 18.8 units.
