SOLUTION: how is 2pi equal to 360 degree and difference

Web20 nov. 2024 · The circumference of a circle is given by the equation C = 2πr. The radian measure of the central angle Θ subtended by the circumference is Θ = 2πr/r = 2π. In degree measure, the central angle subtended by the circumference is 360°. Now we have the relationship between degrees and radians. WebThe radius, diameter, and circumference of a circle are all related through the mathematical constant π, or pi, which is the ratio of a circle's circumference to its diameter. The value of π is approximately 3.14159. π is an irrational number meaning that it cannot be expressed exactly as a fraction (though it is often approximated as ) and its decimal representation …
