1. V = πr²*H
V = π*5²*11
V = 275π j.³

Pc = 2*πrl + 2πr*H
Pc = 2*π*5*5√2 + 2π*5*6
Pc = 50√2π + 60π j.²

2. V = 2 * (1/3π*8²*6) + π*8²*7 = 704πj³
Pc = 2*π*8*10 + 2π*8*7 = 272πj²

1.
P = 2*πrl + 2πr*H
P = 2*π*5*5√2 + 2π*5*6
P = 50√2π + 60π

V = πr²*H
V = π*25*11
V = 275π

2.
P = 2*π*8*10 + 2π*8*7 = 272π

V = 2 *1/3π*64*6 + π*64*7 = 704π
