Within a circle, the units used for measurement are either in degrees or in radians. In addition, radius and diameter are used, which can be in any unit of length, are important dimensions from which size, area, and circumference are obtained.

Who uses a compass and why?
Anyone!Use it do draw a perfect circle, or a circle of the wanted measurements
How do you introduce area of a circle?
Area of any circle in square measurements = pi*radius2
What is the angle measurements of a circle?
The angles around the circumference of a circle add up to 360 degrees.
Do all radii have the same measurements?
Yes, within the same circle
What is the area of a full circle if the diameter is 30?
The area of the circle: pi*15*15 = 225*pi square measurements
What is an area of the circle?
The area of any circle in square measurements = pi*radius2
How do you introduce area of a circle?
Area of any circle in square measurements = pi*radius2

To circumscribed a circle about a triangle you use the?
To circumscribed a circle about a triangle you use the angle. This is to get the right measurements.
What is the angle measurements of a circle?
The angles around the circumference of a circle add up to 360 degrees.
Do all radii have the same measurements?
Yes, within the same circle
What is the area of a full circle if the diameter is 30?
The area of the circle: pi*15*15 = 225*pi square measurements
What is the circumference of a circle with a diameter of 70?
Circumference = 70*pi units of measurements
What is the circumference of a circle if a circle has a radius of 226.08 dm and a diameter of 36dm?
The question does not make sense as you have made an error with the measurements. The diameter is equal to exactly twice the radius. This must always be true in any circle. Your measurements do not agree and thus they are wrong and this question can't be answered with confidence.
What is the circumference of a circle if the radius is 525?
Circumference = 2*pi*525 units of measurements
How would you put diameter in a sentence?
Diameter is useful in determining many measurements about a circle.
What does it mean when it is said that pi is a ratio?
It means that it is the result of dividing two quantities. In this case two measurements: the circumference of the circle divided by the diameter of the circle.
