Answer:11cm

Explanation:

Diameter of the circle= 7cm

so, radius of the circle= 7/2= 3.5 cm

for getting length of the semicircular arc= sircumference of circle / 2

circumference of the circle = 2pi r

lenght of the semicircular arc= 2pi r/2

=pi r

= {22/7}*

=11cm

Answer:

(π/180) x (180) x (7) = (π) x (7) = 21π cm.

The length of the semicircular arc of a circle can be found using the formula:

arc length = (π/180) x (arc degree measure) x (circle's diameter)

If the diameter of the circle is 7cm, then the length of the semicircular arc would be:

(π/180) x (180) x (7) = (π) x (7) = 21π cm.
