Answer:
58.1cm
Step-by-step explanation:
perimeter of a semi-circle = πd/2
d is the diameter
Given
diameter = 37cm
Perimeter of the semi circle = π(37)/2
Perimeter of the semi circle = 18.5(3.14)
Perimeter of the semi circle = 58.09 cm
Hence the perimeter of the semi-circle is 58.1cm
Answer: m=-1.
Step-by-step explanation:

Answer:
length is 7.5 and width is 4.5
Step-by-step explanation:
Its given that perimeter of the triangle is 24 units.
The condition is that length is 3 units more than the width.
l=w+3;
Formula for perimeter is 2(l+w).
so ,
2(w+w+3)=24,
2w+3=12,
w=4.5,
l=w+3=7.5
Hence for the given conditions length is 7.5 and width is 4.5.
2 is the smallest prime factor of 12. 12 can evenly be divided by 2 so that makes 2 the smallest prime factor of 12.
