- D1017.36
Step-by-Step Solution
Three surfaces show: the cylinder's curved side 2πrh = , the cone's curved side πrl = 10 = 188.4, and the circular base π. Total = 1055.04 sq cm. The trap 942 forgets the base the rocket stands on; 1168.08 adds a second circle for the join where the cone sits on the cylinder, but that disc is buried inside the toy; 1017.36 uses the cone's VERTICAL height √ cm in πrl instead of its slant height of 10 cm.
Answer: A) 1055.04
