hnji lyo question solve kro gg.......:)

Answer 1

Answer:

220 mm²

Step-by-step explanation:

Given, Diameter of the capsule = 5 mm.

Then, radius = 5/2 = 2.5 mm.

Height of the cylinder = 14 - 5 = 9 mm.

(i)

Curved surface area = 2πrh

                                  = 2π(2.5)*(9)

                                  = 45π.

(ii)

Curved surface area of two hemispheres = 4πr²

= 4π(2.5)²

= 25π.

Total surface area of two capsules:

= 45π + 25π

= 70π

= 70(22/7)

= 220 mm²

Hope it helps!

Answer 2

Step-by-step explanation:

width of capsule =5mm

radius of hemisphere =2.5mm

c.s.a of hemisphere=2πr square

=275mm square × 2

=550mm square

height of cylinder=14-radis of 2 hemisphere

=9mm

c.s.a of cylinder =2πrh

=131.2mm square

surface area of capsule =c.s.a of 2 hemisphere

+ c.s.a of cylinder

= 682.2mm square

[pie value=22/7]

the surface area of tablet is 682.2mm square
