Step-by-step explanation:

$i) \: \: \: \: tsa = 2\pi \times r(r + h) \\ \\ = 2 \times \frac{22}{7} \times 7 \times (7 + 10) \\ \\ = 44 \times 17 \\ \\ = 748 \: \: {cm}^{2} . \\ \\ ii) \: \: \: \: tsa = 2 \times 250 + 2\pi \times rh \\ \\ \pi {r}^{2} = 250 \\ \\ {r}^{2} = \frac{250 \times 7}{22} \\ \\ h = 7.$
