Find the length of an arc of an 8" radius circle if the arc measures 45°.
Solution:
Given, angle of arc, C = 45°
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)(45°/360°)
= 16π(1/8°)
= 16(3.14)(0.125)
= 50.24(0.125)
= 6.28 inches.
Therefore, the length of the arc is 6.28 inches.
Find the length of an arc of an 8" radius circle if the arc measures 45°.
Summary:
The length of an arc of an 8” radius circle, if the arc measures 45° is 6.28 inches.
