Question

Q5 Q1.) Find the length of the​ arc, s, on a circle of radius r intercepted by a central angle theta. Express arc length in terms of pi. Then round your answer to two decimal places.

Answer 1

s = r
`\theta` = 12 * 190/360 * 2 *
`\pi`

= 38/3 *
`\pi` feet

= 39.79 feet

Answer 2

arc, s = 2
`\pi` * radius * angle / 360
= 2
`\pi` * 12 * 190 / 360
= (38/3)
`\pi`
= 12 2/3
`\pi` feet
= 39.79 feet
