The length of a chord = pi*r*x/180 where x is the angle subtended.
= pi*5*80/180 = 6.98 cm
Depends on what angle the arc subtends at the centre of the circle.
The radius of a circle is the length of the line from the center of the circle to any point on its edge.
The answer depends on the information that you have. If the arc subtends an angle of x radians in a circle with radius r cm, then the arc length is r*x cm.
The length of an arc which subtends an angle of x radians at the centre of a circle with radius r cm is simply rx cm. If you measure angles in degrees then it will be r*x*(pi/180) cm
They are equal in length.

The length of an arc of a circle of radius r, which subtends an angle of x radians at the centre is r*x.
The radius of a circle is the length of the line from the center of the circle to any point on its edge.
The answer depends on the information that you have. If the arc subtends an angle of x radians in a circle with radius r cm, then the arc length is r*x cm.
The diameter of a circle is the length of a straight line that goes through the exact center of a circle. The radius of a circle is the length of a straight line that starts at the exact center and reaches the circle. The radius is half the length of the diameter.
A radius of a circle is a line segment joining the center of the circle to a point on the circle. All such segments have the same length, and this length also called the radius of the circle.
It's the circle's radius which extends from its center to its circumference and it can be of any length you want it to be.
The length of a chord that contains the center of the circle
The length of an arc which subtends an angle of x radians at the centre of a circle with radius r cm is simply rx cm. If you measure angles in degrees then it will be r*x*(pi/180) cm
They are equal in length.
the radius
The diameter of a circle is 2 times the radius. The radius of a circle is the distance from any point on the circle to the center of the circle, and the diameter is the distance from one side of the circle to the opposite side, passing through the center.
