What is the arc length of an arc with radius 14 in and central angle 66°? Show all calculations that lead to the
answer and include units

Answer 1

16.12 inches

Explanation:

To find the arc length of a circle, you can use the formula 2
`\pi`r(θ/360)

θ is the central angle

Substitute Pi for 3.14

Substituting the numbers in the equation, we have 2 × 3.14 × 14 ×
`(66)/(360)`

Put this equation into a calculator and you will get 16.118667, which can be simplified to 16.12 inches.

Answer 2

77π/15 or 16.13

Explanation:

Arc length = 2πr (θ/360)

= 2π(14)(66/360)

= 77π/15 or 16.13
