Answer:
Step-by-step explanation:
7) Given circumference = 24
Angle CED = 78.4 means ARc CD subtends an angle of
156.8 with the centre.
Hence arc length = [tex]\frac{156.8}{360} (24)=10.453[/tex]
8) By circle theorem we have
FC*FC = EC*DC
USing the above
FC*FC =3(1.3) = 3.9
Hence FC = square root of 3.9 = 1.975
9) Length of arc BC = [tex]\frac{146.2}{360} (2(1.9((3.14))=[/tex]=4.845
