# Assuming that a 90° arc has an exact length 4π in., find the length of the radius of the circle.

To determine

To Find:

The length of the radius of the circle.

Explanation

Given:

A 90° arc has length of 4π in.

Calculation:

We know that a circle is made up of four 90° arcs.

Therefore, the circumference of the circle can be obtained by multiplying the arc length by 4.

The circumference of the circle is 44π in.

(i.e.,) 16π in.

The circumference of the circle is C=πd
