2 answers:
Answer:
P = 25.71 cm
Step-by-step 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
Answer:
25.71cm
Step-by-step explanation:
3.142 x 10 = 31.42
31.42/2 = 15.71 (half of the circumference)
15.71 + 10(the diameter).
= 25.71cm
