What is the formula for the diameter or a circle?
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
How do you find a diameter of a circle?
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
What does diameter mean in math terms?
A line that bisects a circle and goes through the center of it is the diameter.
How do you find area of a circle when you have the circumference circle?
Divide the circumference by pi, and that will give you the diameter. Then take half of the diameter (the radius), and plug it into the formula for the area of a circle (A=πr²)
What is the formula for finding circumference and area of a circle?
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
How do you find the of a circumference of circle in math?
the formula is: circumference= p*diameter
What is the formula for the diameter or a circle?
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
What is math formula for figuring out radius of a circle without dividing by diameter?
circumference divided by pie divided by two
What is the formula for the diameter of a circle?
The diameter of a circle is twice its radius, or 2r.
What is the formula for the circumference of a circle if the diameter is 8.70 m?
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
How do you find a diameter of a circle?
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
How to calculate the diameter of a circle when the circumference of the circle is 7?
pi*diameter = circumference Rearrange the formula so as the diameter is the subject of the formula: diameter = circumference/pi diameter = 7/pi = 2.228169203
How do you get the area of a cylinder base in fifth grade math.?
The base of a cylinder is a circle. So we can use the area formula for a circle. Area = πr2 where r is the radius of the circle, and pi is the ratio of the circumference of the circle to its diameter.
If you have the circumference of a circle what is the diameter?
Formula: diameter = pi / circumference
What does diameter mean in relation to math?
It is in a diameter of a circle, which is bassicly means the length of a circle, right through the middle.
How do you work out the area of a circle in a square?
The formula for the area of a circle is pi x radius2. The radius is half the diameter, and the diameter of an inscribed circle is the same as the length of a side of the square.The formula for the area of a circle is pi x radius2.
