Tolong tolong tolong tolong​

1. V = π x r x r x t

V = 22/7 x 14 x 14 x 20

V = 12.320 cm³

2. V = 22/7 x 3,5 x 3,5 x 16

V = 616 dm³

3. V = 3,14 x 5 x 5 x 50

V = 3.925 cm³

Jawab:

no 1. = 12.320 cm³

no 2. = 616 dm³ / 616 liter

no 3. = 3.925 cm³

Penjelasan dengan langkah-langkah:

no 1. V = x r x r x t

           = 22/7 x 14 x 14 x 20

           = 12.320 cm³

no 2. V = x r x r x t

            = 7 : 2

        r = 3,5 dm

            = 22/7 x3,5 x 3,5 x 16

             = 616 dm³

no 3. V = x r x r x t

            = 10 : 2

         r = 5 cm

           = 3,14 x 5 x 5 x 50

           = 3.925 cm³

Semoga membantu
