Find the length of an arc of an 8" radius circle if the arc measures 45 degrees. 2pi, 8pi, 16pi

To find the length of the arc, we will use the formula,

arc length = 2πR (C/360)

where,

R is the radius of the arc, which is 8"C is the central angle, which is 45°

pi is approximately equivalent to 3.14

Applying the formula, arc length = 2πR (C/360)

arc length = 2 (3.14) R (45°/360)

arc length = (6.28) (8") x (0.125)

arc length = (50.24") (0.125)

arc length = 6.28"

The length of the arc is 6.28". 6.28 is also equivalent to 2π, hence, the answer is 2π.
