The arc length of the sector is 7.065 approximately 7.1 cm. Then the correct option is D.
It is a locus of a point drawn equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The central angle of π/2 radians in a circle with a radius of 4.5 cm.
Then the arc length will be
[tex]\rm Arc \ length = \dfrac{\pi /2}{2 \pi} * 2*\pi * 4.5\\\\\\Arc \ length = \dfrac{1}{2} * 3.14*4.5\\\\\\Arc \ length = 7.065[/tex]
Then the arc length is 7.065 approximately 7.1 cm. Then the correct option is D.
