What else can I help you with?
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
What is the diameter of a circle if the circumference is 80 -?
Diameter of a circle = circumference/pi
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.
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.
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.
If the diameter of a circle is 80 what is the circumference?
Diameter of a circle = circumference/pi
What is the diameter of a circle if the circumference is 80 -?
Diameter of a circle = circumference/pi
