Question

Find the length of each Arc List your answer A) exact form and B) approximate form

Answer 1

We have the next formula in order to find the length

`arc\text{ length =}(2\pi r\theta)/(360)`

where

r=5 in

θ=270°

Then we substitute the values

`\text{arc length=}(2\pi(5)(270))/(360)=(15)/(2)\pi\text{ in}`

the exact form is

`(15)/(2)\pi\text{ in}`

the approximate form is

`23.56\text{ in}`
