The area is 12.57 cm2
2cm; the diameter of a circle is twice its radius.

Area = pi*r^2 = 4*pi = 12.6 square cm rounded to 1 decimal place.
Using 3.14 as Pi the area of circle is: 0
Area= pi*r2If the diameter of the circle is 2cm, the A= pi cm2If the radius of the circle is 2cm, then: A=3.14159*4=12.567 cm2
The area is 12.57 cm2
2cm; the diameter of a circle is twice its radius.
The area is 22*pi, or 4pi or approximately 12.56 sq cm.

Length of a radius is always half the diameter of a circle. This means that the circle has a radius of 2cm.
The radius is double the diameter so 4cm.
Diameter of circle = 2 * Radius of the circle.
you half the diamater to get the radius, then you square the radius. Then you times it by 3.14. Always. example. Diameter=4cm then radius =2cm squared=4cm 4x3.14=12.56
Area = pi*r^2 = 4*pi = 12.6 square cm rounded to 1 decimal place.
Using 3.14 as Pi the area of circle is: 0
Diameter of 2 cm radius circle is pi x r2 = 3.1416 x 4 cm2 = 12.5664 cm2 Circumference of 2 cm radius circle = pi x 2r = 3.1416 x 4 cm = 12.5664 cm
