And solve
The picture above
Thanks

Answer 1

Answer:

Volume=254.4

Surface area =226.19

Step-by-step explanation:

Here radius is 3cm and hieght is 9cm.

Volume=

$\pi {r}^{2} h \\ = 3.14 \times 9 \times 9 = 254.4 \: \: {cm}^{3}$

Surface Area=

$2\pi \: r(r + h) \\ = 2 \times 3.14 \times 3(3 + 9) \\ = 2 \times 3.14 \times 3 \times 12 \\ = 226.19 \: {cm}^{2}$

Hope it helps you.
