Answer:
Step-by-step explanation:
An arc is the length along the circumference of a circle that is bounded by 2 radii. I
A central angle in a circle has a measure of 180. This means that the arc subtends an angle of 180 degrees at the center of the circle.
The length of the arc is 8 inches
Formula for the length of an arc is expressed as
Length of arc = #/360 × 2πr
r = radius of the circle
Length of arc = 8 inches
# 180 degrees
π = constant = 3.14
Substituting,
8 = 180/360 ×2 × 3.142 × r
8 = 3.14r
r = 8/3.14 = 2.56 inches
