Step-by-step explanation:
8500 x .09 = 765
8500 + 765 = 9265
4x+60+ x+15=180
5x+75=180
5x=105
x=21

Answer:
The perimeter of the given semi-circle in terms of
is
cm
Step-by-step explanation:
Given that the diameter of the semi-circle is 18cm
That is d=18cm
Therefore radius 

Therefore radius r=9cm
To find the perimeter of the semi-circle :
perimeter of the semi-circle
cm (where r=9 cm )
cm
The perimeter of the given semi-circle in terms of
is
cm
