Answer:
The answer is 16π
Step-by-step explanation:
Firstly , you should keep in mind the the Area of a circle is :πr squared.
Also the diameter is TWICE as much as the radius!
So , 8/2=4 ( radius)
Then , we do 4 x4 ( r squared) =16.
16xπ=16π.
Therefore, answer is 16π!

Answer:
the inverse is 9x + 18
Step-by-step explanation:
switch 'x' with 'y'
y = 1/9x - 2
x = 1/9y - 2
solve for y now, start with multiplying each side by 9
9x = y - 18
y = 9x + 18
f^-1(x) = 9x + 18
