Question

a cuboidal metal of volume 8216cm is melted to make a wire of radius 0.07cm . find the length of the wire​

Answer 1

Answer:

Step-by-step explanation:

Volume of metal = 8316 cm³

Volume of wire =  π r² l

l = length of wire

diameter of wire = 0.07 cm

radius of wire = 0.035 cm

Volume of metal = volume of wire .

8316 cm³ =  π r² l = π 0.035² l

l = 2161965.423119 cm
