Quarter circle
The arc is one quarter of a circle so is 2pir, the other components of the quarter circle are the two radii, so perimeter is 2r+2pir = 2r(1+pi)
A quarter of a circle, formed by two radii forming a right angle at the centre, is called a quadrant.
A quarter circle has one axis of symmetry. An axis of symmetry is a line that divides a shape into two equal halves that are mirror images of each other. In the case of a quarter circle, if you draw a line through the center of the circle perpendicular to the diameter, it will divide the quarter circle into two equal parts that are mirror images of each other.

A quarter of a circle is a turn of 90 degrees'
First quarter. Second quarter. Third quarter. Fourth quarter. Circle center.
AnswerIt's 90*A full circle is 360*, and if you divide that by 4 (quarter) you get 90 Degrees.There are 90 degrees in a quarter of a circle.
A full circle is 360o, so a quarter, (one fourth) of a circle is 90o.

A quarter of a circle is 2/8 of a circle. Add to that an eighth (1/8) of a circle (not eight) and this equals 3/8 of a circle. This equates to 37.5 % of a circle.
The semi-circle shape can be the 1st or 3rd quarter. Perhaps you would want to double check, but I believe that if the "flat" side of the shape is facing to the left, that is the 1st quarter; to the right - 3rd quarter.
Circumference = (4) x (a quarter of a circle) = (pi) x (the diameter)Diameter = (4 x quarter-circle) divided by (pi)Radius = 1/2 the diameter = (2 x quarter-circle) divided by (pi)
, my name is Jon lemen and a quarter is a basic circle
The arc is one quarter of a circle so is 2pir, the other components of the quarter circle are the two radii, so perimeter is 2r+2pir = 2r(1+pi)
A quarter of a circle is a right angle.
