Using a relatively young theory, a team of mathematicians has started to answer questions whose roots lie at the very ...

Arc length is a fraction of circumference. Area of a sector is a fractions of the area of a circle. Both can be calculated using the angle at the centre and the diameter or radius. Practice circle ...

A sector is a fraction of a circle. The angle in the sector is a fraction of 360°. This sector has an angle of θ°. The fraction of the circle is \(\frac{θ}{360}\) The area of the sector will be ...

Computers are working to solve an age-old geometry problem. Humans can’t “square the circle” by hand, which was proven in the 1800s. Computer solutions involve infinity, complexity, and some ...

I’m a journalism student in college, and math is one of the requirements for not only graduation, but also to help me transfer to a four-year school. There are going to be some situations coming my ...
