Answer:
The perimeter of the quarter-circle is 200 cm.
Step-by-step explanation:
Given that the angle of quarter-circle is 90°. So using Length of Arc formula, you are able to find the length of curve :

Let r be radius = 56 cm,
Let θ = 90°




We have already found the arc. Next we have to add up together to find the perimeter :
