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 )
3(x-4) ≥ 5x +2
3*x - 3*4 ≥ 5x +2
3x - 12≥ 5x - 2
-12 + 2 ≥ 5x- 3x
-10 ≥ 2x
2x ≤ -10
x ≤ -5
