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 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 circumference of a circle if it's diameter is 6.625 inches?
The equation for circumference is C=(Pi)*d or 3.14 times the diameter. Therefore, you answer would be 6.625*3.14=20.8025 inches.
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.
What is the equation to find the perimeter of a circle?
Circumference ("perimeter") of a circle = (pi) x (diameter of the circle)
How do you find pi using a equation?
If: circumference = pi*diameter Then: pi = circumference/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
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 equation of Pi?
there is no equation of Pi Circumference divided by diameter
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 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.
How do you write an equation while using circumference?
Diameter = Circumference/pi
What is the equation to get circumference of a circle if you have diameter?
Circumference = Pi x Diameter (Pi equals 3.14)
What is the circumference of a 29 inch tire?
The equation for circumference is Pi(diameter), so the exact value of the circumference of a tire with a 29 inch diameter is 29pi.
How many diameters are in a circumference?
Pi, or 3.14159... Using the equation Circumference = pi * diameter.
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
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.
