Penjelasan dengan langkah-langkah:
V tabung = phi×r×r×t
3080 =22/7 ×7×7× t
3080 =154 ×t
3080÷154 = t
20 =t
V = ⅓πr²t
30.800 = ⅓ × 22/7 × r² × 24
30.800 = 22/7 × r² × 8
30.800 = 176/7r²
[tex] {r}^{2} = \frac{30.800}{ \frac{176}{7} } = 30.800 \times \frac{7}{176} \\ {r}^{2} = 1225 \\ r = \sqrt[2]{1225} \\ r = 35cm[/tex]
