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
If the diameter of a circle is 5 what is the circumference?
The equation for determining the circumference of a circle is circumference = pi x diameter. So if the diameter is 5, then the circumference is pi * 5 = 15.71
What is the mathematical equation you generally use to find the circumference of a circle when you know the diameter?
circumference of a circle = diameter*pi or 2*pi*radius
How do you find the radius of a circle only knowing the circumference?
The equation for finding the circumference of a circle is diameter times pi so reverse it to circumference divided by pi which leaves the diameter. The diameter is twice as big as the radius so divide the diameter by 2 and you will find the radius.
What is the diameter of a circle if the circumference is 80 -?
Diameter of a circle = circumference/pi
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
If the diameter of a circle is 5 what is the circumference?
The equation for determining the circumference of a circle is circumference = pi x diameter. So if the diameter is 5, then the circumference is pi * 5 = 15.71
How does the circumference of a circle change if you double its diameter?
Since the equation for circumference is pi*d then if you double the diameter the circumference will be doubled.
What is the mathematical equation you generally use to find the circumference of a circle when you know the diameter?
circumference of a circle = diameter*pi or 2*pi*radius
What is the equation for determining radius of a circle if you have the circumference?
Circumference = Diameter multiplied by Pi Diameter = Circumference divided by pi Radius = Diameter divided by 2.
What is the equation to find the perimeter of a circle?
Circumference ("perimeter") of a circle = (pi) x (diameter of the circle)
Diameter is 2.5 inches what is circumference?
To get the circumference of a circle, the equation is pi * diameter. So, in this case, it is 2.5 * pi (3.14), or roughly 7.85. So, the circumference of the circle is about 7.85 inches.
What is the equation for the diamiter of a circle?
Diameter = 1/2 of the circle's radius. Diameter = 2 times the square root of (the circle's area/pi) Diameter = the circle's circumference/pi
What is the equation for the circumference and radius?
The equation for circumference is 2(3.14)(r) or 3.14(d) where r=radius and d=diameter. The radius of a circle is half of the circumference, or the distance across the interior of a circle.
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).
Is circumference of a circle the same as the perimeter of a circle?
Yes it is, because both of them are just the distance around the circle, the equation forthe circumference is pi x Diameter.
The wheels circumference is how many times as big as its diameter?
A wheel is in the shape of a circle. The formula for the circumference of a circle is 2πr where r is the radius. But, the diameter of a circle is twice the radius so this equation can be written, Circumference = πd where d is the diameter. The Circumference is therefore π times as big as the diameter, π = 3.142 or 22/7 approx.
