<h3>How to find the area of a sector</h3>

The given diagram is a sector and the formula for calculating the length of an arc is expressed as:

Length of an arc = rβ

where

  • β is the subtended angle
  • r is the radius

Given the following parameters

β .= 45 degrees

r = 6in

Substitute

Length of an arc = 6π/4

Length of an arc = 6(3.14)/4

Length of an arc = 4.71inches

This shows that the length of a will be a different number and the value will be 4.71in
