Answer:
hi mate here is your answer
Step-by-step explanation:
A medicine capsule is in the shape of a cylinder with two hemispheres stuck to each of its ends .The length of the entire capsule is 14 mm and the diameter of the capsule is 5 mm. Find its surface area. (Use π= 22/7
Answer:
given
the shape of the capsule=2 hemisphere+1 cylinder
length of the capsel=14mm
width of the capsel=5mm
to find
the total surface area of the given capsule
solution
the base diameter of the hemisphere=5mm
the radius of the hemisphere=5/2=2.5mm
the height of the hemisphere=2.5mm
the total height of the hemispheres=2.5=5mm
the height of cylinder=14-5=9mm
surface area of cylinder=2×22/7×2.5×9=141.42mm2
curved surface area of one hemisphere=2×22/7×(2.5)2=2×22/7×6.25=39.28mm2
CSA of two hemispheres=39.28×2=78.56mm2
total surface area=141.42+78.56=219.98mm2
