A radian is a different way of measuring angles from a degree. Instead of saying there are 180 degrees in a two right angles, we say there are Pi (3.142) radians in two right angles.
I've never heard of Pia, but it might be Pi multiplied by a.

I think you meant raidan and a Pi, not Pia. A Radian is a unit of angle just like degrees. A circle has 360 degrees or 2 Pi radians. Pi is a greek symbol, two vertical lines connected by a horizontal line at the top. Pi radians is equal to 180 degrees.

A radian (note the indefinite article "a") is a way of measuring angles. More specifically a radian is the length of what an arc on a unit circle would be if you had a section whose angle was the same as the given angle.
Pia is a girl's name. Though since you mention her in the same sentence as "radian", I have to wonder if you meant to say "Pi".

A radian is an angle which is subtended at the center of the arc when the arc length is equal to the length of the circle.
When the complete angle is measured at the circle which is 360 degrees and when it is measured in radians it is equal to 2 pi. Also remember that
pi radians = 180 degrees.
Radain is a unit which is mostly used in the surveying, hydrological surveys .etc.
I hope this will help,
May allah bless you.

A radian is a unit used to measure distance in a circular motion and pi is the ratio of the circumference of a circle to its diameter.

pi is given the Greek symbol Ï where Ï = 22 / 7
2 Ï radians = 360 ° so : -
1 radian = 360 / 2Ï Â° = 57. 3 °
