What is a semicircle arc?
it is the diameter
How many lines of symmetry does a semicircle have?
One. The line of symmetry for a 180 degree arc (a semicircle) is the line that bisects the arc.
What is a half circle arc?
semicircle
An arc with endpoints that are the endpoints of a diameter?
semicircle
For a circle of radius 9 feet find the arc length 's' subtended by a central angle of 18 degrees?
The measure of the central angle divided by 360 degrees equals the arc length divided by the circumference. So 18 degrees/360 degrees=arc length/(9 feet*2pi). 1/20=arc length/18pi feet; arc length=9pi/10 feet. It's refreshing to answer a question that is written with grammatical accuracy!

minor arc
A rod of length L has total charge Q distributed uniformly along its length it's then bent in the shape of a semicircle find the magnitude of the electric field at the centre of semicircle?
At the center of the semicircle, the electric field due to the straight part of the rod will cancel out because of the symmetry. The electric field at the center of the semicircle is only due to the curved part, so you can treat the semicircle as an arc of a circle with charge distributed along its length. You can then calculate the electric field using the formula for the electric field of a charged arc of a circle.
What is a half circle arc?
semicircle
What arc whose measure is greater than a semicircle?
Major arc.
An arc with endpoints that are the endpoints of a diameter?
