Answer 2

$\underline{Gɪᴠᴇɴ:}$

Radius of cylindrical roller = 140 cm

length of cylindrical roller = 1 m = 100 cm

$\underline{Sᴏʟᴜᴛɪᴏɴ :}$

$Volume \: of \: cylindrical \: roller = πr²h \\ \\ = \frac{22}{7} \times (140) {}^{2} \times (100) \\ \\ = \frac{22}{7} \times 140 \times 140 \times 100 \\ \\ = \frac{22}{\cancel7} \times \cancel{140} \times 140 \times 100 \\ \\ = 22 \times 20 \times 140 \times 100 \\ \\ = 6160000 \: cm {}^{3}$
