# Find the perimeter of the adjoining figure, which is a semicircle including its diameter.

**Solution:**

Diameter = 10 cm

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.
