Answer:
Step-by-step explanation:
An arc is a portion of the circle's circumference bounded by 2 radii
The formula for determining the length of an arc is expressed as
Length of arc = θ/360 × 2πr
Where
θ represents the central angle or angle which the 2 radii subtends at the center of the circle.
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
Radius, r = 5 inches
θ = 170 degrees
Therefore,
Length of arc = 170/360 × 2 × π × 5
Length of arc = 4.7222π feet
rounding up to 2 decimal places, it becomes
4.72π feet
