Penjelasan dengan langkah-langkah:
volume tabung=πxr²xt
volume=22/7x7x7x30
volume=22x7x30
volume=154x30
=4.620 cm³
• keliling
k = 2πr
44 = 2 × 22/7 × r
r = 44/2/2 × 22/7
r = 44 ÷ 44/7
r = 44 × 7/44
r = 1 × 7
r = 7 cm
• Volume
V = πr²t
V = 22/7 × 7 × 7 × 30
V = 22 × 7 × 30
V = 154 × 30
V = 4.620 cm³
