Point 'O' is the centre of the ellipse with major axis AB & minor axis CD. Point F is one focus of the ellipse. If OF = 6 & the diameter of the inscribed circle of triangle OCF is 2, then the product (AB) (CD) is
Text Solution
Verified by ExpertsThe correct answer is:
65
(65)
Sol. ae = 6 ⇒ b 2 + 36 = (b + 4) 2 ⇒ 36 = 16 + 8b
b = 
⇒ a 2 = a 2 e 2 + b 2 = 36 + 
= 
a = 
⇒ (2a) (2b) = 65
