Step-by-step explanation:
Area of circle:

By using the area of a circle, we can get the area of a semicircle:

Let's convert the mixed fraction to an improper fraction and then a decimal:
=
= 
Now, we solved for the diameter, to get the radius, we need to divide the diameter by 2:

Now we have the radius, so we can plug in our values and find the area:


Answer:
17+6i

Step-by-step explanation:
2+3i
---------
4+3i
We want to multiply by the complex conjugate of the denominator
4+3i has a complex conjugate of 4-3i
2+3i 4-3i
--------- * --------------
4+3i 4-3i
Lets multiply the numerator
(2+3i) ( 4-3i)
2*4 +4*3i -3i*2 - 3i*3i =
8 +12i -6i - 9i^2
Remember i^2 = -1
8 +6i -9(-1)
17 +6i
Lets multiply the denominator
(4+3i) ( 4-3i)
4*4 +4*3i -3i*4 - 3i*3i =
16 +12i -12i - 9i^2
Remember i^2 = -1
16 -9(-1)

Putting numerator over denominator
17+6i

Answer:
19.26
Step-by-step explanation:
method 1 -
original cost - 12
sell cost - 12×1.5×1.07 =19.26 answer
method 2-
original cost - 12
sell cost increase by 50 % = 12+ 6 = 18
tax 7 % = 18×7/100 = 1.26
total cost = 18+1.26 = 19.26
