Can anyone please complete this..​

Answer 1

Answer:

find the area of circle

Answer 2

width of capsule =5mm

radius of hemisphere =2.5mm

c.s.a of hemisphere=2πr²

= 2*π*(2.5)²

2*π*(2.5)²= 275/7mm²

height of cylinder=14-radius of 2 hemisphere= 14 -5 = 9mm

c.s.a of cylinder =2πrh

=2*22/7*(2.5)*9

=2*22/7*(2.5)*9 = 990/7mm²

surface area of capsule =c.s.a of 2 hemisphere + CSA of cylinder

= 2(275/7)+990/7 = 550/7+990/7 = 1540/7 = 220mm² (Ans)
