Question
Relation between Exradius ,semiperimeter and circumradius can be given by
(r1 is the radius of the circle opposite the angle A)
(r1 is the radius of the circle opposite the angle A)
Answer: Option B
:
B
Relation between Exradius and semiperimeter can be given by, r1=Δs−a where r1 is the radius of the circle opposite the angle A. and it's helpful to remember the identity r1=4RsinA2cosB2cosC2
