Use the x and y values from your point and the h and k from the center to write the equation you need to solve for r. The general form of the equation for a circle is

. We will fill in accordingly:

. Solve for r to get that
you answer is 10 hope this help[s :D
To solve this problem you must apply the proccedure shown below:
1. You have the following points given in the problem above:

2. To find the midpoint, you must apply the formula that is used for calculate it. This is:

Where:

3. Now, you must substitute these values into the formula for calculate the midpoint, as following:

Therefore, the answer is: 
Answer:
300 × (1 + 0.10)^n
Step-by-step explanation:
The computation is shown below:
Given that
The population is 300
And, the population would be increased at a rate of 10% each year
So, the exponential growth function to calculate the daily growth rate is
= 300 × (1 + 0.10)^n
Here n represent the number of years or the time period
So, the above show the exponential growth function
