Question

If an iron piece of a volume 2750 cm3 is drawn out into a wire of radius 5 cm what will be the length of the wire so obtained?

Answer 1

lengthy of wire is 35cm

Answer 2

The length of the wire is 35 cm

Step-by-step explanation:

Radius of wire = 5 cm

Volume of wire =$\pi r^2 h = \frac{22}{7} \times 5^2 \times h$

An iron piece of a volume 2750 cubic cm is drawn out into a wire of radius 5 cm

$2750 = \frac{22}{7} \times 5^2 \times h$

$\frac{2750 \times 7}{22 \times 5^2}=h$

35=h

Hence  the length of the wire is 35 cm
