Question

Tolong jawab dong? pliss besok di kumpulin.makasih

Answer 1

(14*4)+((10-4)*(14-8))=
56+(6*6)=
56+36=92

Answer 2

nomer 1
l = 14- 8 = 6 cm
luas = luas 1 + luas 2
       = p x l + p x l
       = 10 x 6 + 8 x 4
       = 60 + 32
       = 92 cm²

nomer 2
terpakai = 1 - 1/4 = 3/4
volume = 3/4 x π x r² x t
           = 3/4 x 22/7 x 3 x 3 x 21
           = 3/4 x 22 x 9 x 3
           = 3/4 x 66 x 9
           = 1782/4
          = 445,5 cm³
