12.732 (rounded)
The circumference is: 32.1
The area of a circle of radius r is pi*r*r
Divide the circumference by pi, and that will give you the diameter. Then take half of the diameter (the radius), and plug it into the formula for the area of a circle (A=πr²)
If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm
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
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
12.732 (rounded)
The line from the centre of the circle to any point on its circumference
16 pi = almost exactly 50¼
you divide the surface area by the circumference.
The circumference is: 32.1
The cicumference of any circle divided by its diameter is aways equal to pi.
