How do you figure the diameter of a circle from its circumference?
The circumference = pi x r2, and the diameter = 2r. So if you start with the circumference, you divide that number by pi (3.1416), then take the square root. What's left is the value of the circle's radius; double it to get the diameter.
What is the exact radius of a circle with the circumference of thrity six meters?
My understanding is that as the measurement of the circumference of a circle is derived from an equation using "pi" with pi being an indefinite number, the measurement of the circumference of a circle is also an indefinite number, but the figure can be rounded back to a predetermined number of decimal places.
How do you figure out diameter?
Assuming you are talking about a circle:* If you know the radius of the circle, multiply that by 2. * If you know the circumference of the circle, divide that by pi. * If you know nothing, you need to measure either the radius, the diameter, or the circumference.
If the diameter of the circle is 69mm then what is the circumference of this circle?
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
What is the circumference of a 34mm circle?
The circumference of a 34mm circle is: 107 mm
The distance around a geometric figure?
perimeter or circumference The only answer is perimeter. The circumference is the the perimeter of a circle; the distance around a circle.
How do you figure diameter of circle using circumference?
Divide the circumference by pi, and that will give you the diameter.
The perimeter of a polygon is like the circumference of a circle?
Yes it is because the perimeter describe the outside of the figure, when also the circumference describe the outside of the circle.
How do you figure the length of a circle?
The circle's length (or circumference) is determined with the expression C=D(pi).
What is the relationship between the radius and the circumference?
If the figure is truly a circle, then the circumference is (Radius) x (2 pi) .
How do you figure out circumference and radius?
The radius of a circle is from the middle to the edge, or half the diameter. The circumference is like the perimeter of the circle, and the formula is pi times the diameter.
What is the definition of cercumference and radius of pi.?
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.
What dimension is circumference?
the enclosing boundary of a curved geometric figure, esp. a circle. the distance around a circle
What is formula to figure the circumference of a circle?
Circumference = 2 x {pi} x radius = {pi} x diameter
The distance around a figure?
The distance around a figure is called the "perimeter", unless the figure is a circle - in that case, it is called the "circumference".
How do you figure out the radius of a circle with a circumference of 6?
r = C /2 pi
Which geometrical figure encloses the greatest area within the shortest circumference?
A circle.
