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.
How many linear feet in a 3 foot diameter circle?
Arch length, or linear distance of an arch, is equal to: (Angle of Arch in Radians) x (Radius of Arch) So for a complete circle (Arch angle of 360 Degrees) with a diameter of 3 feet (or radius of 1.5 feet) the linear circumference would be: (2 x PI) x (radius) = (2 x PI) x (1.5 ft), where PI = 3.14 radians and represents 1/2 of a complete circle. This is also the equation for a circle's circumference.
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 to find the circumference of a circle?
The formula is pi x the diameter of the circle, which is also pi x (2 x the radius) C = pi * D C = pi * 2r
What is the formula to find the circumference of a circle when the diameter is known?
It is NOT a formula but an EQUATION . The answer is C = pi*d This equation has been known for thousands of years. It can also be in the form of C = 2 pi r NB 2r = d Also A = pi r^(2) for the area of a circle.
What is something with a perfect linear relationship?
A linear relationship is given by the equation y=ax+b Anything which can be modelled by this equation is a linear relationship. For example, the circumference of a circle is pi times d. This can be modelled by y=ax+b where y is the circumference, a is pi, x is the diameter and b is 0. Therefore, the circumference of a circle as the diameter changes is a perfect linear relationship.
How do you measure the circumference of the circle?
The equation for the circumference of a circle is pi times radius squared.
Circumference is 16 times pi what is the diameter?
If the circumference of a circle is 16 linear units times pi, then its diameter 16 linear units.
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 does pi have to do with the area and circumference of a circle?
It is used in finding the circumference and area of a circle. Circumference = 2*pi*radius or pi*diameter measured in linear units Area = pi*radius2 measured in square units
What is the standard equation of the circle?
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
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 equation for the circumference of a circle?
C = 2 * pi * rC is the circumference of the circle;pi is approximately 3.1416;r is the radius of the circle;2r is the diameter, so C = d * pi as well.
What is the circumference of a circle that has a diameter of 16 in terms of pi?
16*pi measured in linear units
What is the equation of the circle standard form?
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
How many linear feet in a 20 foot circle?
Circumference of a circle = 2*pi*radius or pi*diameter Area of a circle = pi*radius squared
