Circum radius of a `DeltaABC` is 3 units, let O be the circum and H be the orthocentre then the value of `(1)/(64)(AH^(2)+BC^(2))(BH^(2)+AC^(2))(CH^(2)+AB^(2))` equals :

In a Delta"le" ABC R=3 (circum radius) Let O be the circum centre and H be the ortho centre then (1)/(64)(AH^(2)+BC^(2))(BH^(2)+AC^(2))(CH^(2)+AB^(2))=

Circumradius of a Delta ABC is 2, o is the circumradius of a Delta ABC is 2, o is the (1)/(64)(AH^(2)+BC^(2))(BH^(2)+AC^(2))(CH^(2)+AB^(2)) is equal to

If in DeltaABC, AB = ( 2a -1) cm, BC = 2sqrt(2a)cm" and "AC = ( 2a+1) cm, then find the value of /_ ABC .

If A = (1, 2), B (2, 3) then the circum radius of DeltaOAB is

Let ABC be an acute angled triangle with orthocenter H. D, E, and F are the feet of perpendicular from A, B, and C, respectively, on opposite sides. Also, let R be the circumradius respectively, on opposite sides. Also, let R be the circumradius of DeltaABC . Given AH.CH.BH=3 and (AH)^(2)+(BH)^(2)+(CH)^(2)=7 . then answer the following : Value of R is
