Answer: 2 A=pi x radius squares so 12.56/3.14159 is the radius squared, Now to find the radius take the square root of that. So we have r squared is 3.9997 or very close to 4 so the radius is very close to 2. We can say it is two in this case we say it is two since we are only dealing with hundreds and 3.9997 rounds to 4

What is the radius of a circle whose area is 1256 square centimeters?

To find the radius of a circle given its area, you can use the formula A = πr^2, where A is the area and r is the radius. In this case, the area is 1256 square centimeters. So, 1256 = πr^2. To solve for r, divide both sides by π and then take the square root. Therefore, the radius of the circle is approximately 20 centimeters.


Where pi is 3.14 find the area of a circle with a radius of 20cm?

Oh, what a happy little question! To find the area of a circle, we use the formula A = πr^2, where A is the area, π is approximately 3.14, and r is the radius. So, for a circle with a radius of 20 cm, the area would be A = 3.14 x 20 x 20 = 1256 square centimeters. Just imagine all the beautiful colors you could paint in that space!
