Answer:

5500  sq. cm

Step-by-step explanation:

r = 7 cm  , h = 24 cm  ∴ l  = √r² + √h²

                                        = √625   =25 cm

 c.s.a 0f c0ne  = π r l

                         =  22/7   x 7 x 25

                        = 550 cm²

∴  area of sheet to make 10 caps  =  550 x 10

                                                        = 5500 cm²
