Answer:

GJK

Step-by-step explanation:

An inscribed angle is an angle formed by two line segments in a circle  that intersect on the circle. The line segments must touch the circle at two points The angle must be on the circle itself.

GIH  is not inscribed because I is in the center of the circle  not on the circle

GJK  is an inscribed angle  GJ and JK   touch the circle at two point and are inside the circle.

IGJ  IG does not touch the circle at two points

JKL   KL  is outside the circle

mixas84 [53]
Because you went from 41.5 to 47.6 when the granite was placed in the graduated cylinder, using displacement:

47.6 - 41.5 = 6.1
