Answer:
Step-by-step explanation:
The ENTIRE 360° arc length of the circle is the circumference
pi * d ('d' is the diameter = 22 ft)
You want a 315° out of 360° fraction of this entire circumference
sooooo:
315 /360 * 3.14 * 22 = 60.45 ft (rounded)
Answer:
arc length ≈ 60.45 ft
Step-by-step explanation:
the length of the arc is calculated as
• length = circumference of circle × fraction of circle
length = 2πr × [tex]\frac{315}{360}[/tex] ( r is the radius )
given r = 11 ft and using π ≈ 3.14
length = 2 × 3.14 × 11 × [tex]\frac{7}{8}[/tex]
≈ [tex]\frac{2(3.14)(11)(7)}{8}[/tex]
≈ [tex]\frac{483.56}{8}[/tex]
≈ 60.45 ft ( to 2 decimal places )
