Pertanyaan Terlampir.​

Jawaban:

b. 1.800

Penjelasan dengan langkah-langkah:

v tab = 36cm³

rumus v = πr²t, → kita pakai ¼πd²t

sehingga, v tab diperbesar

= ¼πd²t

= 36.5².2

= 1.800 cm³

Penyelesaian:

V=36cm³

--------------------

Jika d=5kali diameter asli dan t=2kali yang asli

----------------------------------------

V=Πr²t

V=¼Πd²t

Karena Πr²t=¼Πd²t

Maka

V=¼Π(5d²)×2t

V=36×5²×2

V=36×25×2

V=36×50

V=1.800cm²(B.)
