V=192,5 cm³
t.tabung= 2,5 dm=25 cm
tanya: r=
jawab:
V=L.ling×t.tabung
192,5 cm³=π.r².25cm
r²=192,5 cm³ / π.25 cm
r²=7,7 cm²/π
r²=7,7 cm²/22:7
r²=(7,7 cm²/1) : (22/7)
r²=(7,7 cm²/1) × (7/22)
r²=7,7 cm² .7/22
r²=2,45 cm²
r=√2,45 cm
192,5 = 3,14 x r² x 25
192,5 = 78.5r
r² = 192,5/78.5
r² = 2,45
r = √2,45
r ≈ 1,6 cm
