Answer: i think its 4 im not sure
Step-by-step explanation:
So, to find the find the amount of fencing required, or the circumference of the gardening, pot...
Area = pi * r^2
125 square feet = pi *r^2
125/ pi = r^2
39.79 = r^2
root square of 39.79 = r
6.31 = r
To find the circumference, the formula is: pi * D (or Pi * r * 2)
therefore,
C = pi * 6.31 *2
C = 39.65 feet
therefore, 39.65 feet of fencing is needed.
hope this helps

Answer: Explanation below.
Step-by-step explanation:
First of all you need to know how to convert a logarithm into an exponential expression. The property is:
This is the same as:
Example 1:
We are trying to find what to raise 9 to, in order to get a result of 9.
When you have same bases, you equal exponents.
Therefore;
Example 2:
In this case, we have to make sure both sides have the same base. 32 can have a base of 2 if expressed as: which is 2*2*2*2*2
Rewriting this example we have;
Since we have the same base, we equal exponents.
Therefore;
Example 3:
729 can have a base of 3 if expressed as:
