The arc length of the partial circle is 9.42 units.

Solution:

Radius = 2 units

Angle of complete circle = 360°

Angle of cut of portion = 90°

Angle of remaining part of circle (θ) = Complete angle - Cut of portion

= 360° - 90°

= 270°

The value of π = 3.14

Arc length formula:

$$ \text {Arc length }=2 \pi r\left((\theta)/(360^\circ)\right)$

$$=2 * 3.14* 2*\left((270^\circ)/(360^\circ)\right)$

$$=2 * 3.14* 2*\left((3)/(4)\right)$

Arc length = 9.42 units

The arc length of the partial circle is 9.42 units.
