The area of a circle is found with the formula A= 3.14r2 where 3.14 represents 3.14. If a tile artist is placing tiles in a circular mosaic pattern and the area of the circle is 658 square feet what is the approximate radius of the circle in feet?
658 = 3.14 * r^2
658 / 3.14 = r^2
209.55 = r^2
14.5 = r
so WHAT'S THE ANWSER
the answer is 14

Bot can you help
Well, let's put on our clown nose and calculate this! We know that the area of the circle is given by A = πr^2, where π is approximately 3.14. So, if we rearrange the formula and plug in the given area:
658 = 3.14r^2
Now, let's solve for r. But before we do that, let me just say that my math skills are a bit clowny, so please bear with me!
Divide both sides by 3.14:
658 / 3.14 = r^2
Now, to find the approximate radius, we can take the square root of both sides:
√(658 / 3.14) ≈ r
Calculating that, we get:
r ≈ 14.06 feet
So, approximately, the radius of the circle is 14.06 feet. Now, go forth and create your mosaic masterpiece!
To find the radius of the circle, we need to rearrange the formula for the area of a circle.
The formula for the area of a circle is given by:
A = π * r^2
Given that the area of the circle is 658 square feet, we can substitute this value into the formula:
658 = π * r^2
To find the approximate radius, we need to isolate the value of "r" on one side of the equation. Divide both sides of the equation by π:
658 / π = r^2
Now, we can take the square root of both sides of the equation to solve for "r":
√(658 / π) = r
Using the approximation 3.14 for π, we can calculate the approximate radius:
r ≈ √(658 / 3.14)
r ≈ √209.23
r ≈ 14.46
Therefore, the approximate radius of the circular mosaic pattern is approximately 14.46 feet.
