Using 3.14 as Pi the area of circle is: 0
6 cm.
29.76
A = 28.27cm2
A 3 centimeter diameter circle has an area of 7.068 cm2
Using 3.14 as Pi the area of circle is: 28.259999999999998
(3cm)2 x pi = 28.274 cm2
The area of a 3 cm circle is: 7.069 square cm
Pi x 3cm x 3cm= Area
Diameter = 1/2 of the circle's radius. Diameter = 2 times the square root of (the circle's area/pi) Diameter = the circle's circumference/pi
If you do not have the area, what do you have? The radius is half the diamiter The radius is PieR2 Worked backwards if you know the circumfrence.
A circle with a radius of 5.
The diameter of a circle is twice its radius.
