Answer:
mFG = 67r ( Where r is the radius of the circle)
∠ECF = 67°
Step-by-step explanation:
i) m FG
Join CG
∠GCF=67°
(As FG=ED and equal chords subtend equal angle at center)
Now The length of the minor arc is given by the formula
m arc FG =

∠C=67
m arc FG = 
m arc FG = 67r
Where r is the radius of the circle.
2. ∠ECF = 67°
It is because of the rule which says that equal chords subtend equal angle at center
DE = EF
Hence ∠DCE = ∠ECF

Answer:
254.34 in.²
Step-by-step explanation:
area = πr²
given, radius = 9 cm
according to formula
→ 3.14 × (9)²
→ 3.14 × 81
→ 254.34 in.² ans.
hope this helps you !
