Circle also forms and important part of the Quantitative Aptitude section of various exams like RBI Grade B, RBI Assistant, SEBI Grade A, IBPS SO, IBPS PO, IBPS Clerk, SBI PO, SBI Clerk, LIC AAO, SSC CGL, SSC CHSL and many more. Therefore, it forms an essential part of the Quantitative Aptitude syllabus.

In Quant, a circle is a two-dimensional geometric shape that is defined as the set of all points that are a fixed distance (called the radius) from a central point (called the center) in a plane. The distance around the circle is called the circumference, while the distance from the center to any point on the circle is called the radius.

The formula for the circumference of a circle is C = 2πr, where "C" represents the circumference, "π" represents the mathematical constant pi (approximately equal to 3.14159), and "r" represents the radius. The formula for the area of a circle is A = πr^2, where "A" represents the area.

Circles are important geometric shapes in Quantitative Aptitude and have many practical applications in everyday life, including in architecture, engineering, physics, and astronomy.
