Your goal when solving problems like these are to get V by itself. Meaning, on one side of the equal sign. So first you are to add -2 over to the side with the 4. Then multiple that by 11. To undo the division
The formula of the area of a circle is :

You know that the area is 1256.
So :

Divide both sides by

:

<span> take the square root of both sides in order to obtain r :

Answer:
3.825 kg apples.
Step-by-step explanation:
Let x kg be the amount of apples stand owner had initially.
We have been given that during the first hour of operation the farm stand owner sold 15% of the apples he had. Then the amount of sold apples will be:
On the second hour he sold 20% of the remaining apples. So the amount of sold apples on the second hour will be 20% of 0.85x.

During the second hour 25.5 kg of apples were sold, so we can set up an equation as:



So, stand owner had initially 150 kg of apples.

On the third hour he sold 25% of the remaining apples. So the amount of sold apples on the 3rd hour will be 25% of 0.68x

As remaining apples were sold 5% more each following hour.
Let us substitute x=150 into above equation we will get,
Therefore, 3.825 kg of apples were sold during the 4th hour.
