The radius is the distance from the center to the outside. The diameter is the distance from the outside to the outside, passing through the center - in other words, twice the radius.
If you draw a line from the center of a circle to the edge of a circle, you have drawn the radius of the circle. If you draw a line from the edge of a circle through the center of the circle and on to the edge on the opposite side, you have drawn the diameter of a circle. The radius of a circle is one half the diameter of a circle.
to determine the radius if you only have the diameter, you divided the diameter by 2. then there you have it ! you have the radius !
The area of a circle if the diameter was s 7ft is 38.48ft
The Moon's diameter is 2,159 mi (3,475 km).
s the equator and the diameter the same thing?
Only circles (or spheres) have a diameter
Only circular shapes have diameter not Squares.
Multipy by 2 for the diameter
circumference = pi*diameter
The radius is half the diameter.
If you have only the arc length then you cannot find the diameter.
