Volume =
Maka,
V =
9240 = 22/7 × r² × 15
9240(7/22) = r² × 15
2940 = r² × 15
2940/15 = r²
196 = r²
r = √196
r = 14
Rumus :
Luas sisi tabung = 2 × × r × (r + t)
Jadi, Luas sisi tabung adalah
Luas sisi tabung = 2 × × r × (r + t)
Luas sisi tabung = 2 × 22/7 × 14 × (14 + 15)
Luas sisi tabung = 88 × 29
Luas sisi tabung = 2552 cm
