Question

An electrician bent a section of copper wire into a partial circle as shown. The dimensions are

given in feet (ft).


2.5 f


880


2.5


ft


What is the length of the section of wire to the nearest hundredth of a foot?

Answer 1

Explanation:

3.84

Answer 2

Length = 3.84 feets (nearest hundredth)

Explanation:

The length of section of wire can be obtyaiejd using the length of of a arc formular :

Length of arc = θ/360° * 2πr

Radius, r = 2.5 feets

Length of arc = (88/360) *2πr

Length of arc = (88/360) * 2π*2.5

Length of arc = 0.244444 * 15.707963

Length of arc = 3.8397

Length = 3.84 feets (nearest hundredth)
