Answer 1

Step-by-step explanation:

$h = 1.5 \: m \\ d = 80 \: cm \\ r = \frac{80}{2} = 40cm \\ r =0 .40 \: m \\ total \: surface \: of \: cylinderical \: co ntainer \\ = \pi \times r(r + h) \\ = \frac{22}{7} \times 0.4(0.4 + 1.5) \\ = \frac{22}{7} \times 0.16 + 0.60 \\ = 0.50 + 0.60 \\ = 1.1 {m}^{2} \\ = 1.1 \times \frac{5}{100} \\ = 0.22 {m}^{2} \\ = 1.1 + 0.22 = 1.32 {m }^{2} \\ 1 {m}^{2} = 3350 \: rupees \\ 1.32 {m}^{2} = 3350 \times 1.32 = 4422rupees \: \\ thi \: is \: the \: final \: answer$
