Answer:
The length of the circular arc is 8.64 inches
Step-by-step explanation:
Length of circular arc (L) = central angle/360° × 2πr
central angle = pie/4 = 45°, r (radius) = 11 inches
L = 45°/360° × 2 × 3.142 × 11 = 8.64 inches (to two decimal places)
Well, basically there are
acute angle, right angle, obtuse angle ..
and also we use concurrent angles, corresponding angles, alternate angles, vertically opposite angles,..
