Answer 1

$volume \: = \pi {r}^{2}h \\ = \frac{22}{7} \times 7 \times 7 \times 25 \\ = 3850 \: {cm}^{3} \\ \\ csa = 2\pi \: rh \\ = 2 \times \frac{22}{7} \times 7 \times 25 \\ = 1100 {cm}^{2} \\ tsa = 2\pi \: rh + 2\pi {r }^{2} \\ = 2 \times \frac{22}{7} \times 7 \times 25 + 2 \times \frac{22}{7} \times 7 \times 7 \\ = 44 \times 25 + 44 \times 7 \\ = 1100 + 308 \\ = 1408 {cm}^{2}$
