Why is the diameter of a circle always twice the length of the radius?
A circle is the locus of points that are equidistant from a fixed point. As a result, all radii of the circle must be of the same length. A diameter is a straight line that goes from the circumference to the centre and on to the circumference on the other side. Thus it is a radius from the circumference to the centre and then another radius from the centre to the circumference. And since these are the same, it is 2 radii in length.
What is the circumference of a circle?
The circumference is the distance around the circle, its "perimeter."The circumference of a circle is equal to π times the diameter of the circle (C = πd), or π times twice the radius of the circle (C = 2πr).The circumference is the distance around itIf you know the diameter (width) of the circle, you can use the formulaCircumference= Diameter x pi (approx 3.1416)Example : if a circle has a diameter of 5 cm then the circumference is 5 x π =5π (about 15.7 cm)The actual formula relates to the radius of the circle, which is half the diameter.Radius Formula : C = 2πr (2 pi times the radius)As long you remember the formula you should be fine....Circumference = 2 * pi * rOr pi * dwhere r = radius & d = diameter of the circle.Also pi (=3.143) can be roughly put down as 22/7 if you more comfy with fractions than the decimals.the equation is 2*pi*rr being the radius
How big is 50m diameter?
A 50-meter diameter is equivalent to the distance across a circle from one edge to the other passing through the center, measuring 50 meters in length. In terms of area, a circle with a 50-meter diameter would have a radius of 25 meters and an area of approximately 1,963.5 square meters (πr^2). This size can be visualized as a circle with a radius of 25 meters or a little over 82 feet.
How do you increase the size of a circle?
Increase the length of the radius
If the diameter of a circle is doubled does the area double?
The area will be four times as big. If a circle is going to retain its shape as a circle it has to get twice as big not just from left to right, but from top to bottom also. So you're doubling the size in both directions.
How mayny times the radius is the diameter?
The diameter of a circle is twice the size of its radius.
What is the total diameter of a circle?
It is twice the size of a circle's radius.
What is the are of circle with radius 32.25mm?
If the radius of a circle is twice the diameter. The outer diameter of a circle the size of a circle. 32.25 mm = 1.27 inches
Is the diameter of a circle is always greater than the radius of a circle?
Yes because it is twice the size of the radius.
How are the diameter and radius the same?
They are not the same. Diameter is twice the size as radius.
What is the relationship of radius todiameter?
In a circle its radius is half the size of its diameter.
How do you decrease he size of a circle?
By reducing its radius or diameter.
Why is the diameter of a circle always twice the length of the radius?
A circle is the locus of points that are equidistant from a fixed point. As a result, all radii of the circle must be of the same length. A diameter is a straight line that goes from the circumference to the centre and on to the circumference on the other side. Thus it is a radius from the circumference to the centre and then another radius from the centre to the circumference. And since these are the same, it is 2 radii in length.
What are three different size circle?
Each circle with a different radius (or diameter or circumference) is a different size circle.
What happens to the diamenter of a circle if you triple the radius?
It will be twice the size of the tripled radius
If the diameter of a circle is 8 feet the radius will be?
The radius would be 4 feet I know this because the diameter is always 2x the size of the radius.
Circle to square feet?
The answer requires information on the size of the circle: its radius, diameter or circumference.
