Based on the attached figure, the perimeter of the given figure is 25.71 cm.
How to find the perimeter of the figure
To find the perimeter of the figure, follow this steps
Diameter = 10 cm
Since diameter is 10 cm , the radius will be its half
thus;
Radius = 10/2 cm = 5 cm
Perimeter of the given figure = Circumference of semi-circle + diameter
= πr + D
= 22/7 × 5 cm + 10 cm
= 110/7 cm + 10 cm
= 25.71 cm
Thus, the perimeter of the given figure is 25.71 cm.
