Area = pi*52 = 78.53981634 or rounded to 2 decimal places as 78.54 square cm
A = ~78.53cm2
314.1592653589793 cm3
Area of circle = Pi/4 x D2 Pi/4 = .7854 Area = .7854 x 14 x 14 = 153.94 square feet (rounded)
Area = (Pi/4)*diameter2 = .7854*4.452 = 15.5528 sq.cm.
Using 3.14 as Pi the area of circle is: 78.5
A = ~78.53cm2
314.1592653589793 cm3
Area of circle = Pi/4 x D2 Pi/4 = .7854 Area = .7854 x 14 x 14 = 153.94 square feet (rounded)
Area = (Pi/4)*diameter2 = .7854*4.452 = 15.5528 sq.cm.
78.54 square cm
The area of a 10cm circle is 314.16cm2 ( squared)
Using 3.14 as Pi the area of circle is: 78.5
Square the diameter and multiply by .7854 (1/4 of pi).
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
The circle's area is 314.159 cm2
