the answer is 20.54
It depends on the ratio of what of the circle? Its circumference, diameter, area?
Circumference of a circle = 3.14 x d 3.14 x 8 = 25.12 Therefore the circumference of a circle with the diameter of 8cm is 25.12cm.
The diameter of a circle may found by dividing the circumference by pi. 8cm/3.1416=2.546cm
Circumference of a circle: 2*p*radius or pi*diameter
C = ~25.133 cm
The radius is 1.27cm
Area of a circle = pi*radius2
Area of any circle = pi*radius squared
The area of a circle with a circumference of 9.42 is about 7.06.
You dived the area by the circumference of the circle.
No,Circumference is like the perimiter and Area is the whole circle.
