Answer 1

Answer:

which shapes tsa and volumne we have to find

Answer 2

Answer:

you forget what is the figure but from your information it is look like a cylinder

$r \: = 7.7cm \\ h = 10cm\\ tsa \: of \: cylinder = 2\pi \: r(r +h ) \\ = 2 \times \frac{22}{7} \times 7.7 \times (7.7 + 10) \\ =44 \times 1.1 \times 17.7 \\ = 856.68 {cm}^{2} \\ \\ now \: volume \: of \: cylinder = \pi {r}^{2} h \\ = \frac{22}{7} \times 7.7 \times 7.7 \times 10 \\ = 22 \times 11 \times 7.7 \\ = 1863.4 {cm}^{3}$
