It is the radius
A straight line passing from side to side going through the middle of a circle or sphere is a diameter.
No. Every circle on the sphere whose center is also the center of the sphere is a great circle. If the circle's center is not also the center of the sphere, then the circle is a small circle.
The diameter joins together the circumference of the sphere and it passes through the center of the sphere.
A radius is the distance from the centre of a circle (or sphere) to its circumference (or surface). It is a straight line and has dimensions [L]. It has only a length, no volume. So there is no such furmula.
4*pi*r2. because surface area is equal to circumference of circle.
Diameter is the length of a straight line passing through the center of a circle or sphere and connecting two points on the circumference of the circle or the surface of the sphere. Circumference is the length of the closed curve of a circle.
If you mean "radius," it's a straight line from the center to the circumference of a circle or sphere.
Circumference is the enclosing boundary of a curved geometric figure, especially a circle. Radius is a straight line from the center to the circumference of a circle or sphere. Pi is the numerical value of the ratio of the circumference of a circle to its diameter and does not have a circumference or radius of its own.
radius
A line segment extending from the center of a circle or sphere t o the circumference or bounding surface.
Diameter is distance across a circle or sphere, circumference is the distance around a circle or sphere
Radii is the plural of radius. A radius is the length of a line segment between the center and the circumference of a circle or sphere.
A straight line passing from side to side going through the middle of a circle or sphere is a diameter.
No. Every circle on the sphere whose center is also the center of the sphere is a great circle. If the circle's center is not also the center of the sphere, then the circle is a small circle.
The radius of a sphere joins the center of the sphere to its circumference.
R (radius) X2. The radius is half the circle from the center of the circle. The diameter is just straight across.
Infinity because the circumference of the circle is the same as the circumference of the sphere.
