the answer is 20.54
It depends on the ratio of what of the circle? Its circumference, diameter, area?
The radius is 1.27cm
A = 5.093 cm2
Area of any circle = pi*radius squared
Clarity please!!!! 'Circumference of what??? Also what does the 8 cm represent . diameter, radius, diagonal etc., !!!!

Using 3.14 as Pi the area of circle is: 200.96
It has a circumference of 50.3cm
To find the diameter of a circle with an 8cm circumference, you can use the formula C = πd, where C is the circumference and d is the diameter. Plugging in the given circumference of 8cm, you get 8 = πd. To solve for d, divide both sides by π, giving you d = 8/π. Therefore, the diameter of a circle with an 8cm circumference is approximately 2.55cm.
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.
That would depend on its radius which has not been given but the area of a circle is pi times radius squared
C=3.14*d<----diameter d=r*2 ex: what is the circumference of a circle if the radius is 4cm? 4*2=8cm 3.14*8=25.12cm c=25.12cm
