tabung yg tingginya 10cm mempunyai volume 6.160 cm3. jari jari alas tabung tersebut adalah.... (phi = 22/7)

diket
t = 10cm
volume = 6.160cm³
π = 22/7

Volume tabung = π ×r² × t
6160cm³ = 22/7 × r² × 10
6160cm³ = 22/7 × 10 × r²
6160cm³ = 220/7 × r²
r² = 6160cm³ × 7/220
r² =
[tex] \sqrt{196} [/tex]
r = 14cm.

Maaf kalau salah:)

Volume = alas x tinggi
6160 = alas x 10
Alas = 616 cm

Pi r^2 = 616
22/7 r^2 = 616

22 x r^2 = 4312
R^2 = 4312/22
R = akar 196
R = 14 cm
