the answer is 20.54
It depends on the ratio of what of the circle? Its circumference, diameter, area?
The radius is 1.27cm
Circumference of a circle: 2*p*radius or pi*diameter
A = 5.093 cm2
Area of any circle = pi*radius squared
15
Using 3.14 as Pi the area of circle is: 200.96
It has a circumference of 50.3cm
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
The diameter of a circle may found by dividing the circumference by pi. 8cm/3.1416=2.546cm
