Quarter Circle Calculator

Quarter Circle:

A quarter circle is a one fourth part of a full circle.

In above figure the curved shape ‘aboa’ is a quarter circle of radius R.
O is center of the quarter circle and its Central Angle is ∠aOb = 90°

Perimeter v/s Circumference:

The peremeter of any shape is the total length of all its sides. The circle have infinite sides, So its shape’s total lenght is called circumference(L). We can calculate the Radius(R), Circumference(L) and Area(A) of a quarter circle if any one of its parameter is given. A quarter circle has no Diameter(D).
