Circle

A circle is a simple shape in Euclidean geometry. It is the set of all points in a plane that are at a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves so that its distance from a given point is constant. The distance between any of the points and the centre is called the radius.

A circle is a simple closed curve which divides the plane into two regions: an interior and an exterior. In everyday use, the term "circle" may be used interchangeably to refer to either the boundary of the figure, or to the whole figure including its interior; in strict technical usage, the circle is only the boundary and the whole figure is called a disk.

A circle may also be defined as a special ellipse in which the two foci are coincident and the eccentricity is 0, or the two-dimensional shape enclosing the most area per unit perimeter squared, using calculus of variations.

Biography

1977–2009: Early life and career beginnings

Pusha T was born Terrence Thornton on May 13, 1977, in The Bronx borough of New York City. Thornton and his family soon relocated to Norfolk, Virginia, where he and his brother, Gene 'No Malice' Thornton, grew up. In 1992, Terrence and his brother Gene formed the duo Clipse. With help from American record producer and fellow Virginian Pharrell Williams, the duo eventually signed to Elektra Records in 1997 and released Exclusive Audio Footage, their only album under that label. Of the two brothers, Terrence was more open to features, appearing on Kelis' 1999 single "Good Stuff" and Nivea's 2001 single "Run Away (I Wanna Be with U)", respectively. In 2004, he and his brother launched their record label imprint, Re-Up Records and formed hip hop group Re-Up Gang, along with fellow rappers Ab-Liva and Sandman. In 2006, they released their third studio album and their most commercial album, Hell Hath No Fury, which was praised by critics. After one more album as the Clipse in 2009, both No Malice and Pusha T announced that they were taking time off from the duo to focus on their own respective solo projects.
