Answer:

Volume = 175.93km ^3

Surface Area = 753.97km ^2

Step-by-step explanation:

Cylinder surface area =A=2πrh+2πr2

Volume = V=πr2h

We plug in

Area = 2 x π x 8km x 7km =2π 56 = 351.85km ^2

= 351 858 377 m^2

+ 2πr2 = 2 x π x 64 = 402.12km^2

Surface Area = 2π 56 + 2π x 64

402.12 + 351.85 =753.97km ^2 = 753 97 8377 m^2

Volume = π x 8 x 8 x 7 = 448π = 1407.43km ^2

= 140.743m^3
