What is semi circle?

In mathematics, a semicircle is a one-dimensional locus of point that forms half a circle.

Now it is given that,

radius of semi circular pendant, r= 8 centimeters

hence, the circumference of semi circular pendant = 2πr

⇒circumference of semi circular pendant = 2*3.14*8

                                                                       = 50.27 centimeters

since, semicircular pendant is use on a keychain.

∴approximate length of the wire = circumference of semi circular pendant

⇒∴approximate length of the wire =  50.27 centimeters

Hence, the approximate length of the wire she attached to the pendant is 50.27 cm.
