Question

Ming argues that the length of a will be half of the measure of the length of 6 since 45° is half the measure of 90°. Charlene argues that the length of a will be a different number.
What is the length of a?

Answer 1

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

How to find the area of a sector

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
