616 = pi x r x r
616 = 3.1415 x r x r
616/3.1415 = r x r
196.0846 = r x r
So r = square root of 196.0846 = 14.003 cm

approximately 7 centimeters.
For a radius of 5 centimeters the area are 78.53981633974483 square centimeters.
10.48cm
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.
Total surface area = 1847.26 sq cm.
