Does a semi circle have one side?
Being half of the circumference of a circle, a semi circle has one side
What is circumference and diameter and radius?
The circumference is the distance AROUND a circle. The diameter is the distance ACROSS a circle. The radius is the the distance FROM THE CENTER of the circle (same thing as one-half of the diameter).
How do you calculate the radius from the diameter of a circle?
The radius is one -half of the diameter. It is the distance from the circle center to any point on the circumference.
What is the circumference of a circle that has a diameter of one and a half inch?
Use the formula c=d(pi)
Why are radius and diameter different?
The radius is half of the diameter. The radius of a circle is the distance from the centre to the circumference. The diameter of a circle is the length of a straight line from one point on the circumference to another, passing through the centre of the circle.

What are its parts of circle?
Circumference is the perimeter of a circle Diameter is the length spanning a circle cutting through its center Radius is half the length of a circle's diameter Tangent is a straight line that touches a circle's circumference at one point Arc is part of a circle's circumference Chord is a straight line joining any two points of a circle's circumference Sector is the area enclosed by an arc and two radii Segment is the area enclosed by arc and a chord Circle's circumference divided by its diameter is equal to the value of pi Area of a circle = pi*radius squared There are 360 degrees around a circle

How many curved line in a circle?
A circle has one curved line and it is its circumference
What is the distance traveled by a boy who walks on a circular track and reaches back to the starting point often completing one round?
The distance traveled by the boy would be the circumference of the circle, which is calculated using the formula: Circumference = 2πr, where r is the radius of the circle. When the boy completes one round on the circular track, he travels a distance equal to the circumference of the circle.
Why is an inscribed angle that intercepts a semi-circle a right angle?
It is the consequence of one of the circle theorems and in some books, it is considered a theorem itself. The underlying proposition is that the angle subtended at the circumference of the circle by any arc of a circle is half the angle subtended at the centre. In the case of a semicircle, the arc is the half circle and the angle at the centre is the one that the diameter makes at the centre of the circle ie 180 degrees. So the angle at the circumference is half that ie 90 degrees.
What is the circle circumference formula?
In order to calculate the circumference of a circle one must use a specific formula. The mathematical formula is C = D x 3.14. This translates to the circumference being equal to the diameter multiplied by 3.14, which is the equivalent to pi.
What is A line segment drawn through the center of the circle with endpoint on the circle?
A line segment drawn through the centre of a circle and having endpoints on the circumference of that circle is called the diameter. Notably, a line segement with one endpoint at the centre of the circle and one anywhere on the circumference of the circle is called the radius, and is exactly half the length of the diameter.
How do you find the radius and circumference of a circle?
Draw a line that passes through the center of the circle (if the center is not marked, you can still find it by various means of geometrical construction, if you have a compass, or by slowly pulling a ruler down through the circle and seeing where the measurement of the circle is largest). The line that passes through the center, going from one side of the circumference to the other, is the diameter. The radius is simply half the diameter and can be measured directly, with a ruler. Once you have that figure, you can calculate the circumference. The circumference is equal to pi times the diameter, or two pi times the radius. Pi is equal to approximately 3.1415 which is close enough for all usual purposes.
