Area = circumference squared...
You do circumference divided by 4,...
and then divide that by Pi.
The area is 346.639 cm2
You must find the circumference. First measure a line through the cirle. Then that is the diameter then multiply the diameter by 3.14 then you have the area! Hope that helped!
pi*radius squared
circumference of a circle = 2*pi*radius or pi*diameter
circumference = pi*diameter
The line from the centre of the circle to any point on its circumference
12.732 (rounded)
use the circumference formula of a circle circumference of a circle=2*pi*r pi=22/7 r-radius of a cirle Now the answer for the problem is 11.69
16 pi = almost exactly 50¼
The circumference is: 32.1
Area = (circumference squared)/(4 pi)
you divide the surface area by the circumference.
