Answer:

25.71cm

Explanation:

3.142 x 10 = 31.42

31.42/2 = 15.71 (half of the circumference)

15.71 + 10(the diameter).

= 25.71cm

Answer:

P = 25.71 cm

Explanation:

Perimeter of semicircle = πD/2

Where D=10 cm

P = (3.142)(10)/2

P = (3.142)(5)

P = 15.71 cm

Complete Perimeter of Semicircle = P + Diameter

= 15.71 + 10

= 25.71 cm
