The arc length of the partial circle is 7.5π
<h3>Calculating arc length</h3>
From the question, we are to determine the arc length of the partial circle
The length of an arc can be calculated by using the formula

Where
is the length of the arc
is the angle subtended
and r is the radius
From the diagram,
θ = 270°
r = 5
Putting the values into the equation, we get



OR 7.5π
Hence, the arc length of the partial circle is 7.5π
