volume tabung yg tingginya 5dm diketahui 6.930 liter.jari jari alas tabung tersebut adalah

Jari - Jari Alas :
V = πr²t
6.930 = 22/7 × r² × 5
6.930 = 110/7r²
r² = 6.930 × 7/110
r² = 441
r = √441
r = 21 cm

Maaf Kalau Salah

V = π r ^2 × t
6.930 = 3,14 × r^2 × 5
r^2 =>> 6.930 / 110/7
r^2 = 6.930 × 7/110
r^2 = 441
r = √ 441
r = 21 cm
