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


Answer: 1.51
Step-by-step explanation:


w + 7.1 = 8.61
w + 7.1 - 7.1 = 8.61 - 7.1
w = 1.51
Answer:

Step-by-step explanation:
There are two black slices.
So, out of 6 slices, you can land on 2 slices.
2 out of 6
2 / 6
1 / 3
Answer:
Function A. <em>nonlinear</em>
Function B. <em>linear</em>
Step-by-step explanation:
Function A is nonlinear because the y values are changing at a nonlinear rate. To get from 0 to 1, the value is increased by 1. However, to get from 1 to 8, it increases by 7, which is different than before.
Function B is linear because the equation models a linear function. You can test this by drawing a table of values similar to Function A:

You can see the y values change at a linear rate of -1 constantly.
