Arcs in Circles Worksheets

What Are Arcs in Circles? The boundary of the circle is known as its circumference. When we take portion of this circumference, we get a curved line, and this curved line is what we call arcs in circles. Other curved shapes such as ellipses also have arcs. When the arc length is half of the circle, we it semicircular arc. The length of an arc can be calculated using the formula; arc length = s = 2πr (angle of arc / 360) Another formula for arc length is; arc length= s = r θ .

Claude Debussy (1862-1918) French composer

"Music is the arithmetic of sounds as optics is the geometry of light." Classification of mathematical problems as linear and nonlinear is like classification of the Universe as bananas and non-bananas.
