If you have a circle with an area of approximately 45 square feet, what is a good estimation for the radius of the circle? (4 points)
Step 1: What is the formula for finding the area of a circle?
Step 2: What would be the first step in solving for the radius?
Step 3: What would be the second step in solving for the radius?
Step 4: The approximate radius would be about?
choose from here:
1. multiply by TT on each side of the equation
2. multiply by 2 on each side of the equation
3. divide by TT on each side of the equation
4. subtract TT from each side of the equation
5. 2.1 feet
6. 7.16 feet
7. C=2TTr
8. A=2TTr^3
9. 3.8 feet
10. take the square root of each side of the equation
11. square each side of the equation
12. 205 feet
13. divide by 2 on each side of the equation
Step 1: The formula for finding the area of a circle is A = πr^2.
Step 2: The first step in solving for the radius would be to rearrange the formula to solve for r: r = √(A/π).
Step 3: The second step in solving for the radius would be to substitute the given area of approximately 45 square feet into the formula.
Step 4: The approximate radius would be about 3.8 feet.
Therefore, the correct answer is: 3.8 feet.
choose from the chosen numbers
The answer is: 3.8 feet.
what is question 2 and 3
Question 2: multiply by 2 on each side of the equation
Question 3: divide by π on each side of the equation
is this correct?

There seems to be a mistake in the formula for finding the area of a circle, as it should be A = πr^2, not A = TTr^2. The correct steps to solve the problem are:
Step 1: The formula for finding the area of a circle is A = πr^2.
Step 2: The first step in solving for the radius would be to rearrange the formula to solve for r: r = √(A/π).
Step 3: The second step in solving for the radius would be to substitute the given area of approximately 45 square feet into the formula.
Step 4: The approximate radius would be about 3.8 feet.
Therefore, the correct answer is indeed 3.8 feet.
