If you have a circle with an area of approximately 45 square feet, what is a good estimation for the radius of the circle?
question 1: what is the formula for finding the area of a circle?
question 2: what would be the first step in solving for the radius
question 3: what would be the second step in solving for the radius
question 4: the approximate radius would be out...
1. The formula for finding the area of a circle is A = πr^2, where A is the area and r is the radius.
2. The first step in solving for the radius would be to rearrange the formula to solve for r: r = √(A/π).
3. The second step in solving for the radius would be to plug in the given area of 45 square feet into the formula: r = √(45/π).
4. Solving for the approximate radius would give us r ≈ √(45/π) ≈ √(14.32) ≈ 3.78 feet. Therefore, a good estimation for the radius of the circle would be approximately 3.78 feet.
