Surface area = 756. 3 square m

Volume = 1408 cubic m

Step-by-step explanation:

lateral \: area = 2\pi \: rh \\  = 2 \times  \frac{22}{7}  \times  \frac{16}{2}  \times 7 \\  = 22 \times 16 \\  = 352 \:  {m}^{2}  \\  \\ surface \: area = 2\pi \: r(h + r) \\  = 2 \times 3.14 \times 8(7 + 8) \\  = 6.28 \times 8 \times 15 \\  = 6.28 \times 120 \\  = 756.3 \:  {m}^{2}  \\  \\ volume = \pi {r}^{2} h \\  =  \frac{22}{7}  \times  {8}^{2}  \times 7 \\  = 22 \times 64 \\  = 1408 \:  {m}^{3}  \\
