Question

Volumul cilindrului cu raza de 8 cm si h(inaltimea) de 1,2 dam .

Answer 1

8 cm = 0,008 dam

V = Ab × h

= π×r²×h

= π×0,000064dam²×1,2dam

= 0,0000768π dam³

= 0,000241152 dam³

Answer 2

Răspuns:

1,2 dam=1200cm(h); r=8cm

V=3,14×r^2×h

V=3,14×8^2×1200

=241152cm

sau 8 cm=0,008 dam(h)

V=3,14×0,008^2×1,2=3,14×0,000064×1,2=0,0000241152
