Step-by-step explanation:

The length of arc EC, in the given circle is: 37.3 cm

What is the Length of an Arc?

Length of arc = ∅/360 × 2πr

Given the following:

Radius (r) = FA = 23 cm

∅ = m∠EFC = 180 - 87 = 93°

Length of arc EC = 93/360 × 2π(23)

Length of arc EC = 0.258 × 144.5

Length of arc EC = 37.3 cm
