If the centroid of tetrahedron OABC where A,B,C are given by (a,2,3),(1,b,2) and (2,1,c) respectively is (1,2,−2), then distance of P(a,b,c) from origin is

If the centroid of tetrahedron OABC where A ,B, C are given by (a, 2, 3) ,(1 ,b, 2) and (2, 1, c) respectively is (1, 2, -1) then distance of P(a, b, c) from origin is

If the centroid of the tetrahedron OABC where A,B,C are the points (a,2,3),(1,b,2) and (2,1,c) be (1,2,3) and the point (a,b,c) is at distance 5sqrt(lambda) from origin then lambda^(2) must be equals to

If the controid of the tetrahedron OABC where A,B,C are the points (a,2,3), (1,b,2) and (2,1,c) be (1,2,3) and the point (a,b,c) is at distance 5sqrt(lambda) from origin, then lambda^(2) must be equal to.

Centroid of the tetrahedron OABC, where A=(a,2,3) , B=(1,b,2) , C=(2,1,c) and O is the origin is (1,2,3) the value of a^(2)+b^(2)+c^(2) is equal to:

If the centroid of the tetrahedron O-ABC, where A-=(alpha,5,6), B-=(1,beta,4) and C-=(3,2,gamma) is G(1,-1,2) , then: alpha^(2) + beta^(2) + gamma^(2)=

If the centroid of the triangle formed by (a,1,3) ,(-2,b,-5) and (4,7,c) is the origin then (a,b,c) =

If the origin is the centroid of triangle ABC, with vertices A(a,1,3), B(-2,b,-5) and C(4,7,c). Find the values of a,b and c.
