Yes it is.
Linear simply means that the degree (or number of powers) of the variable is 1.
In this case the variable is the radius "r" and it occurs to the first power ... so the
equation
C=2 times pi times r
is linear in r.

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 equation of the circle standard form?
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
What is the circumference of a circle that has a diameter of 16 in terms of pi?
16*pi measured in linear units
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
