if you have a radius in a circle do you use A=(3.14)d2
circumference is pi times diameter (8.6 +8.6) x 3.1415926=___mm round off answer as needed
You draw a circle around a circle.
Its the distance from the center of the circle to the edge of the circle.
The cord of a circle that contains the center of that circle is a diameter of that circle.
A = 50.265 square units.
if you have a radius in a circle do you use A=(3.14)d2
raidus means a scientific answer and is to be measured for something for example the earth it is 6400km raidus
circumference is pi times diameter (8.6 +8.6) x 3.1415926=___mm round off answer as needed
The relationship between the radius and area of a circle is as follows: Area of circle = 3.14 x Radius x Radius or 22/7 x Radius x Radius
64 pi ie just over 201 sq cm
diameterA straight line between one point on a circle's edge and another is called a chord. A chord that goes through the centre is called the diameter.The disance across a circle is called a diameter, if you half that it will be called the raidus
The distance half way across a circle is the circle's radius.radias
6378.1 kilometres. Which is 3969 miles.
300 feet
The sun's radius is approximately 696340 Km.
circumference is diameter times 3.14 diameter is raidus times 2 1 times 2 equals 2 3.14 times 2 equals 6.28 circimference is6.28
