In the diagram EFGH is a circle centre O FH is ... - JAMB Mathematics 2000 Question
A
32cm
B
26cm
C
20cm
D
16cm
correct option: b
\(\bigtriangleup\)OEN = \(\bigtriangleup\)OGN
OE = OG = r(radii)
(r - 8)2 + 122 = r2
r2 - 16r + 64 + 144 = r2
16r = 64 + 144 = r2
16r = 64 + 144 = 208
\(\frac{208}{16}\) = 13cm
FH = 2FO = 2OH = 2R
= 2 x 13cm
= 26cm
OE = OG = r(radii)
(r - 8)2 + 122 = r2
r2 - 16r + 64 + 144 = r2
16r = 64 + 144 = r2
16r = 64 + 144 = 208
\(\frac{208}{16}\) = 13cm
FH = 2FO = 2OH = 2R
= 2 x 13cm
= 26cm
