Oh, what a happy little question! To find the area of a circle, we use the formula A = πr^2. With a radius of 4.6 centimeters, we simply plug that into the formula: A = π(4.6)^2. After a little calculation, we find the area to be approximately 66.45 square centimeters. Just like that, we've created a beautiful area calculation together!

Area = Pi(r)2 - A circle with a radius of 4.6 centimeters has an area of 66.48 square centimeters.
For a radius of 5 centimeters the area are 78.53981633974483 square centimeters.
This circle has an area of 11,310 cm2
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.
