Question

Tolong jawab nomor 33 36 40..!!

Answer 1

33. 10+10+7+1/2 x 22/7 x diameter
= 27 + 1/2 x 22/7 x 7
= 27 + 11 = 38 (a)

Answer 2

33. K = 7 cm + 10 cm + 10 cm + (1/2 π . d)
         = 27 cm + (1/2 . 22/7 . 7)
         = 27 cm + 11 cm
         = 38 cm
36. K = 35 cm + 35 cm + ( 1/2π . d)
         = 70 cm + (1/2 . 3,14 . 44)
         = 70 cm + 69,08
         = 139,08
40. LSP = (3x4) + (6x4) + (5x6) + (3x6)
             = 12 + 24 + 30 + 18
             = 84 cm²
