Answer:
The length of the arc is 2.62 cm
Step-by-step explanation:
Let us use the formula
Length of arc =
\frac{\theta}{360} (2\pi r)
where
r is the radius, the given unit is in cm
θ is the arc of the circle, the unit is in degrees
Given information
θ = 30°
r = 5 cm
L = ?
Solving the problem
Let us solve the length of the arc using the given formula
Length of arc =
\frac{\theta}{360} (2\pi r)
Then, substitute the given data
Length of arc =
\frac{30}{360} [2\pi (5)]
Length of arc = 2.62 cm
Therefore, the length of the arc is 2.62 cm
