Answer:
The perimeter of the given semi-circle in terms of  is
 is
 cm
 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 (where r=9 cm )
 cm
 cm
The perimeter of the given semi-circle in terms of  is
 is
 cm

Answer:
x=8a
Step-by-step explanation:
3/a x-4=20
We need to solve for x
Add 4 to each side
3/a x-4+4=20+4
3/a x = 24
Multiply each side by a/3 so we can get x alone
a/3 *3/a x = 24 * a/3
x = 8a
