Find the length of an arc of 40° in a circle with an 8 inch radius.
Solution:
Given, angle of arc, C = 40°
Radius of circle, r = 8 inches
We have to find the length of an arc of a circle.
Length of an arc = 2𝜋r(C/360°)
So, length of an arc = 2𝜋(8)(40°/360°)
= 16𝜋(1/9°)
= 16(3.14)(0.111)
= 50.24(0.111)
= 5.58 inches.
Therefore, the length of the arc is 5.58 inches.
Find the length of an arc of 40° in a circle with an 8 inch radius.
Summary:
The length of an arc of 40° with an 8 inch radius is 5.58 inches.
