Does two radii equal one diameter?
That's right. In a circle, the length of a diameter will be the same as twice the length of a radius.
What is the difference between a radii and radius?
Well, honey, "radii" is the plural form of "radius." So, if you're talking about one of those lines from the center of a circle to any point on its circumference, that's a radius. But if you're feeling fancy and need to talk about more than one, then you're dealing with radii. It's as simple as that, darling.
A circle will have different radii but they will all be the same length?
Yes, all radii of a circle have the same length. One often thinks of the radius as being this length.
What is the formula for radius of sphere?
The radius of a sphere is equal to one-half the diameter. If the volume of the sphere is known, then the radius (r) is equal to the cube root of 3/4 of (Volume/pi).
What is the formula for the radius of a cylinder?
rc = d/2Radius equals diameter divided by 2.In a right circular cylinder there are 2 circles - one of the base and one on the top of the cylinder. If we are going to get the radius of one of them, it will be equal to one-half the measure of the diameter of the whole circle, or r = d/2.
Do two radii equal one diameter?
Yes. D = 2R
Does two radii equal one diameter?
That's right. In a circle, the length of a diameter will be the same as twice the length of a radius.
What is the sum of radii?
2 radii = one diameter
What are radii?
Radii is the plural of the word radius.If you have a circle, bisect it with a straight line - that is the diameter. Cut that in half - that is the radius. The radius is the distance from the center to the edge of the circle.A radius is one half the diameter of a circle ( the straight line distance from one point of the edge of a circle to the other side, directly in the middle). The plural form of radius is radii.
What is halfway across the circle called?
It is the radius. More than one are radii. All the way across is the diameter.
What will be the diameter of a hexagon be with 16 inch sides?
The diameter of a hexagon will be any segment that joins two vertices of the hexagon and passes through its center. Since each of the angles of a hexagon is 120 degrees, than any triangle, which is formed by one side of the triangle and two radii, is an equilateral triangle, and so the lengths of radii are also 16 inches. Thus, the diameter (the sum of two radii) is 32 inches.
What is a solar radii?
A solar radii is a unit of measurement used to describe the size or distance of an object relative to the Sun. It is often used in astronomy to compare the size of stars or planets to that of the Sun. One solar radii is equal to the radius of the Sun.
How do you divide a circle into 3 parts using only a confectionery ruler with no markings?
Draw a diameter on the circle from A to B and mark the midpoint, C (center of the circle). Mark the midpoint, D, of one of those radii (halfway between center and edge). Draw a perpendicular line to the diameter from D to the two edges of the circle, E and F. Draw radii from E to C and F to C. Lines AC, EC, and FC mark the three equal parts of a circle.
What would the diameter of two circles of equal size be relative to the diameter of one circle of equal area?
it would be the diameter of the smaller circle times sqrt 2
How many centimeters in 48 inches diameter?
The answer is 121.92 centimeters in diameter. One inch is equal to 2.54 centimeters. To convert inches into centimeters, multiply the inches by 2.54.
What is the radius of a circle if the diameter is 8 inches?
The radius is the distance from the center of the circle to its edge. The diameter is a straight line passing from one point on the edge to another which passes through the center. Draw these and you will see that the diameter is really just two aligned radii, so the radius is always exactly half of the diameter.
How many inches in 1 diameter?
Diameter is not a unit of measure. It would be like asking how many inches in 1 highway. However, decimeter is a unit of measure. One decimeter is equal to one-tenth of a meter. There are 3.937 inches in a decimeter.
