The area is 12.57 cm2
The area is 22*pi, or 4pi or approximately 12.56 sq cm.
The formula to calculate is: πD (or 2πr) On calculator, π=3.141592654 So it would be 12.56637062cm
2cm; the diameter of a circle is twice its radius.

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

A sector with a radius of 2 cm can't have an arc of 18 cm. If the radius is 2 cm, then the entire circumference of the whole circle is a little less than 12.6 cm. Strange as it may seem, the area of that whole circle is a little less than 12.6 cm2 .

Length of a radius is always half the diameter of a circle. This means that the circle has a radius of 2cm.
