Step-by-step explanation:
The base function is given as
This graph opens up and has its vertex at the origin.
When we shift the graph of this function down by 9 units, its vertex is now at (0,-9)
The equation of this new graph is
The formule is about area of a circle.
We need to solve the equation for x. Where x is the radius of the circle.
In order to solve it for x, we need isolate it for x on left side.
So, first we need to get rid pi from left side.
On dividing both sides by pi, we get
Taking square root on both sides, we get
