The diameter of a circle is its largest chord. Arc of a Circle: An arc is a part of the circle, with all its points on the circle. It is a curve that is a part of its circumference. An arc that connects the endpoints of the diameter has a measure of 180° and it is called a...
In geometry, Arc is the part of circumference of a circle. It is a smooth curve with two end points. The length of the arc that subtend an angle (θ) at the center of the circle is equal 2πr(θ/360°). Learn more about arc at BYJU’S.
Arc of a CircleAn arc is a portion of the boundary of a circle. Suppose you put your finger on the boundary of the circle. If you move your finger on the boundary of the circle and the distance you cover is less than the perimeter of a the circle, what you end up with is an ...
It is the measure of the outside boundary of the circle. So, thelength of the circle or the perimeter of the circleis called Circumference. Arc of a circle The arc of a circle is a portion of the circumference. From any two points that lie on the boundary of the circle, two arcs c...

What is an arc in geometry?Geometry:Geometry being a wide concept, includes a huge number of theorems, properties and basics which give shape to various geometrical figures. Thus, to know all about the basics- the building blocks, by the help of which these figures hold their properties, is...
If a circle has a radius of 5 cm and an arc of length 3 cm, what is the measure of the central angle in radians? A. 0.6 radians B. 0.8 radians C. 1.2 radians D. 1.5 radians 相关知识点: 试题来源: 解析 A。弧长公式 l = rθ(l 是弧长,r 是半径,θ是圆心角弧度),则θ =...
where {eq}C {/eq} is the circumference of the circle If a circle circumscribed a rectangle then the diameter of the circle is equal to the diagonal length of the rectangle. If {eq}L {/eq} and {eq}W {/eq} are the length and width then the diagonal of...
AGreat Circleis any circle that is formed by a plane that passes through the center of the Earth. The equator and the circles created by the meridians form Great Circles. The shortest line between two points on the Earth's surface is always the arc of a Great Circle. Because of this, ...
