What is an Arc? An arc is a part of a circle. For instance, a half of a circle (called a semicircle) is an arc, as is a quarter-circle. An arc that is less than half of the circle it is part of (i.e. less than a semicircle) is called a minor arc, while an arc that ...
What is the formula for the length of an arc? If the subtended angle is given in radians, the formula for arc length is s=r*theta, where "s" is the arc length, "r" is the radius of the circle, and "theta" is the subtended angle. If the angle is instead given in degrees, the...

The formula for the area of a circle is A = πr2, where r is the radius of the circle. The unit of area is the square unit, for example, m2, cm2, in2 etc. In this article, we will learn terms related to circles, like radius, diameter, perimeter, area of the circle, etc. ...
As you begin calculating areas, you may notice that you need some of the same components that perimeter formulas call for, such as length and width. So, what is the area formula for a rectangle, a triangle and a circle? Learn how to calculate the area for each using the area formulas ...
There is a formula that relates the arc length of a circle of radius, r, to the central angle, θθ in radians. Formula for S=rθS=rθ The picture below illustrates the relationship between the radius, and the central angle in radians. The formula is S=rθS=rθ where s ...
