A magician wishes to create the illusion of a 2.49 m tall elephant. He plans to do this by forming a virtual image of a 42.0 cm tall model elephant with the help of a concave spherical mirror.

A) If the model must be placed 3.00 m from the mirror, what radius of curvature is needed? (Include the sign of each answer.)

B) How far from the mirror will the image be formed? (Enter a negative value if the image forms behind the mirror.)
