Be filled with this water.4. Two solid cylinders, one with diameter 60and height 30 cm and the other with radius 31cm and height 60 cm, are melted and recastedinto a third solid cylinder of height 10 cmFind the diameter of the cylinder formed.TL1​

Answer»

R1=d/2=60/2=30cm. h1=30cm

R2=31cm. h2=60cm

r3=? h3=10cm

V1+v2=V3

π r1^2 h+π r2^2 h=π r3^2 h3

π(r1^2 h1+r2^2 h2)=π r3^2 h3

r1^2 h1+r2^2 h2=r3^2 h

(30)^2 (30)+(31)^2 (60)=r3^2 (10)

27000+57660/10=r3^2

84660/10=r3^2

r3^2=8466

r3=√8466

r3=92.01cm

d3=2r3

d3=2(92.01)

d3=184.02cm
