take it apart mentally
cylinder+2hemispheres
2hemispheres=2half spheres=1 sphere
15=radius of sphere+legnth of cylinder+radius of spehre
diameter=5
d/2=5/2=r
15=2.5+legnth+2.5
10=legnth of cylinder
surface area of sphere=4pir^2
surface area of cylinder (not including bases) is pidh
sphere radius=2.5
SA=4pi2.5^2
SA=4pi6.25
SA=25pi
SA=78.5
sphere area
SA=5pi10
SA=50pi
SA=157
add them
78.5+157=235.5 mm^2
