Question

Asap! find the length of the arc

Answer 1

A.
`(21)/(4) \pi\ \space\ in`

Explanation:

The formula for arc length is:

arc length = rθ

where:

r is the radius = 7 in

θ is the central angle in radians = 135 ×
`( \space\ \pi\ )/(180)` = 3/4 π

Substituting these values into the formula:
arc length = 7 in × 3/4 π

=
`(21)/(4) \pi\ \space\ in`
