Answer:
⇒ answer B
Step-by-step explanation:
* Lets revise some transformation
- If the function f(x) translated horizontally to the right
by h units, then the new function g(x) = f(x - h)
- If the function f(x) translated horizontally to the left
by h units, then the new function g(x) = f(x + h)
- If the function f(x) translated vertically up
by k units, then the new function g(x) = f(x) + k
- If the function f(x) translated vertically down
by k units, then the new function g(x) = f(x) – k
* Now lets solve the problem
∵ f(x) = x^1/3
- f(x) shifted 2 units to the right
∴ f(x) = (x - 2)^1/3
- f(x) shifted 2 units down
∴ f(x) = (x - 2)^1/3 - 2

The area of a shape is the amount of space it can occupy.
<em>The value of r is 13</em>
From the question (see attachment), we have:
--- area of the shaded region
--- the width of the shaded region
The area of the complete circle would be:
The area of the small circle is:
So, the area of the shaded region is:
Substitute known values
Substitute 2 for w
Expand
Open brackets
Cancel out line terms
Divide through by 4
Factor out pi
Divide through by pi
Substitute 22/7 for pi
Using a calculator, we have
Solve for r
Hence, the value of r is 13
