10.479 cm
Area of circle = 78.54 sq cm => Radius of circle = 5 cm => Diameter of circle = 10 cm => Side of square = 10cm => Area of square = 100cm2
Area of a circle in square cm = pi*radius2
Area of a circle in square cm = pi*radius squared
A circle with a radius of 19 cm has an area of 1,134.11 square cm.
10.479 cm
Radius is the square root of (345/pi) = 10.47935641 cm
Approximately 10.479cm
The area of a 3 cm circle is: 7.069 square cm
Area = 345 = pi*r2 So r = 10.48 cm
