given
width of capsule=diameter of base of cylinder=diameter of base of hemisphere=7mm
radius of common base=3.5mm
CSA hemisphere=2×3.14×3.5×3.5=0.7693cm^2
given
length of capsule=12mm
length of cylinder=length of capsule_2 (radius of hemisphere=12-2 (0.35)=11.3cm
radius of cylinder=0.35cm
CSA of cylinder=2×3.14×0.35×11.3=24.837cm
surface area of capsule=CSA of cylinder+2 (CSA of hemisphere)
=24. 837+2 (0.7693)
=26. 37cm^2

Answer:
height of capsule=12-3.5-3.5
height of cylinder =5
total surface area= vol of 2.hemisphere+vol of cylinder
