How do you use the diameter to find the circumference of a circle?
Multiplying the diameter by pi (approx 3.1416) will give you the circumference of the circle.
How do you find out the the diameter of a circle if knowing the circumference?
Divide the circumference by the value of Pi - that will give you 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)
How do you calculate the diameter and the circumference of a circle?
Doubling the radius will give the diameter and times this by pi will give the circumference of the circle.
How do you find the radius for a circle when they give you the circumference?
You divide the circumference by Pi (about 3.1416). This gives you the diameter. Divide the diameter by two to get the radius.
How do you find the circumference with no radius or diameter?
They would have to give you enough information to eventually get the diameter. If they gave you the area of a circle and asked for the circumference, you can determine the radius, and from the radius the diameter, and then the circumference. If they said "What is the circumference if the area of a circle is 36pi?" Area of a circle is pi*r2, which would give us a value for r = 6 Diameter is 2*r, or = 12. Circumference is d*pi, or 12pi
How do you figure diameter of circle using circumference?
Divide the circumference by pi, and that will give you the diameter.
If you Give a circle with a diameter of 4 what is the circumference?
the equation for the circumference of a circle is 2*radius*pi, or since the radius is half of the diameter 2*radius=diameter, we can simplify the equation to the circumference of a circle=diameter*pi
What are the dimensions of circle?
The three most common ways to describe the dimension or size of a circle is either the diameter or the radius or the circumference (perimeter).When the circumference is given then dividing that by Pi will give you the diameter (circumference / Pi = diameter).
How do you find the diamiter of a circle?
well you can divide the circumference by pi (3.14) and it will always give you the diameter or you could measure it.
How do you find the radius of a circle if you know the circumference?
Given the circumference, divide the circumference by pi (3.1416) to give the diameter of the circle, then divide by 2 to find the radius (half of the diameter).Since C = (pi) D and D = 2r, then r = C/2piSee related links for more help with circles.
How do you find circumference if you have radius?
First of all, let's define circumference. Circumference is the diameter of a circle times pi (3.14) So it would take 3.14 diameters to go around the circumference of a circle. A radius is from the center of a circle to the outside. It is half the length of the diameter. So, take the radius and double it. That will give you the diameter. Take the diameter and multiply it by pi. Pi is the button on your scientific calculator that looks like Stonehenge. If you do not have a pi button, 3.14 will give you a rough estimate.
