Do all circles have a diameter?
yes
What is the retationship between the circumference and the diameter?
What is the relationship between the circumference and the diameter? Answer The circumference divided by pi gives the diameter. d = C / pi An alternate way to express the above answer. For all circles, pi is the ratio of the circumference to the diameter pi = C / d
Are all circles similar?
Yes, all circles are similer, they all have 1 line, all the same shape, any quarter of a circle will always be 25%, but it the line is bigger they still have differances and similarities, e.g a circle can have a radius of 25cm while another can have a radius of 93984389569349billion miles
The diameter of a circle is 12 cm what is its radius?
Well, honey, if the diameter is 12 cm, all you gotta do is cut that bad boy in half to get the radius. So, the radius would be 6 cm. Easy peasy lemon squeezy!
Why is half the diameter the radius?
A radius is a straight line from the circumference (boundary) of a circle to the centre. A diameter is a straight line that goes from the circumference to the centre and then continues until it reaches the circumference of the other side. In a circle, all points on the circumference are the same distance from the centre. As a result, the second part of the diameter is the same as the first. In other words, diameter = radius + radius = 2*radius.
The diameter of a big circle is 42 feet what is the ratio of the circle's radius to it's diameter?
Radius = 1/2 of diameter.The ratio is 1/2 = 0.5.That's true for all circles, from microscopic to humongous, doesn't matter.
Is the ratio of circumference to the diameter of all circles always the same?
Yes
What did early civilizations notice about the ratio of circumference to diameter?
They noticed circumference/diameter was a constant ratio applicable to all circles no matter whattheir sizes were
What is pi radius and diameter?
The radius of a circle is the distance from the center to any point on the circle. The diameter is twice as much; it is the length of a line segment from one point on a circle to another point on it that passes through the center. Pi is a constant, equal to approximately 3.1416 (the exact value is irrational), which is defined as the ratio of the circumference of any circle to its diameter (all circles are similar so the ratio is always the same).
Do concentric circles have the same circles?
No. You can only define a circle by radius, diameter, area, perimeter. Concentric circles have the same centre, therefore, if they were the same circles with the same radius, then they would all lie on top of each other and be effectively one circle.
What is the relationship between circumference and pi?
In any circle, the product of pi and the diameter will be the circumference. That is because pi is the ratio of the diameter of a circle to its circumference. Here is the equation: c = pi x d
If a circle has a radius of 8 centimeters what is the diameter?
For all circles , however, large or small The diameter is twice the radius. Diameter(d) equals(=) radius(r) plus(+) radius(r). d = r + r d = 2r . NB The diameter is a straight line from the circumference to the centre , and then out to the opposite sided circumference. It is NOT an angled line centred on the central point.
Which is more diameter or radius?
The diameter. The diameter is all the way across the circle, the radius is half of the diameter
What is the radius of a circle that is 24 feet across?
Oh, what a delightful question! To find the radius of a circle, we simply divide the diameter by 2. So, if the circle is 24 feet across, the radius would be 12 feet. Just imagine all the happy little circles you can create with that radius!
Do all circles have a diameter?
yes
How do you find the radius in a circle when all you have is the diameter.?
The diameter is equal to half of the radius. So take the value of the diameter and divide it by two and that is your radius.
What is the retationship between the circumference and the diameter?
What is the relationship between the circumference and the diameter? Answer The circumference divided by pi gives the diameter. d = C / pi An alternate way to express the above answer. For all circles, pi is the ratio of the circumference to the diameter pi = C / d
