Answer:
8.5cm
Step-by-step explanation:
The shape is a circle which was cut into congruent sections.
The approximate height of the parallelogram is the radius of the circle which was cut.
Area [tex]=72.25\pi cm^2[/tex]
Area of a circle = [tex]\pi r^2[/tex]
Therefore:
[tex]\pi r^2=72.25\pi \\r^2=72.25\\r=\sqrt{72.25}\\r=8.5 cm\\$The approximate height of the figure is 8.5cm[/tex]
