Answer:
Length of arc: 9.04cm
Explanation:
Circumference = pi x diameter (or radius times 2 in this case)
C = pi x (7 x 2)
C = pi x 14
C is equal to around 43.98cm
In order to find the length of the arc, you use the central angle and turn it into a fraction, and then multiply that fraction by the circumference.
74 degree angle/ 360 degrees --> 74/360
74/360 x 43.98 = 9.04cm
