The length of a will be a different number and the value will be 4.71in
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
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
