A circle that has a radius of 4.6 centimeters has an area of 66.5 square centimeters.
A circle with a radius of 18 centimeters has an area of 1,017.88 square centimeters.
The radius of a circle whose area is 3.14 square centimeters is: 1 cm
The radius are 7 centimeters and the area are 153.93804002589985 square centimeters.
For a radius of 5 centimeters the area are 78.53981633974483 square centimeters.
A circle with a radius of 18 centimeters has an area of 1017.88 square centimeters.
Area = Pi(r)2 - A circle with a radius of 12 centimeters has an area of 452.39 square centimeters.
10.48cm
The area is about: 50.27 square centimeters.
The side of the square is equal to the diameter of the circle, in this case 2a so the perimeter is 8a cm.
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.
