Question

Calcule o Volume de cada cilindro reto e marque a alternativa correta
a) 95 b) 58,875
a) 125 b) 56,875
a) 100 b) 54,875
a) 100 b) 58,875

Answer 1

Resposta:

a)V= ( area da base= A=πr² )x(altura=h)

V=π2²(8) V=32π π=3,14 32((3,2-0,06)=10,24-0,32(6)=102,4-1,92=

32(3,2-0,6)=102,40-1,92)=100,48

b) Vb=(Va=100)(5/2)²(3/8)=100(25)3/4(8)=25²(3)/8=625(3)/8

625/8=78,

65

0,32(6)=1,92

32π(5/2)²(3/8)=4(2,5)(2,5)3π=75π

Vb=25π3=75π

RESP a) V=32π b) V=75π
