On a spool of mass

0.5 kg

is winded an aluminium wire of length

100 m

. Choose the function that describes the dependence of a mass of the spool with the wire

m

(in kilograms) on a diameter of the wire

d

(in millimetres). Wire density is

2 700 \frac{k g}{m^{3}}

Hint: The density of an object is defined as the ratio of the mass and the volume of the object.

m = \frac{27 π}{400} d^{2} + 0.5

m = 67500 π d^{2} + 0.5

m = \frac{27 π}{400} d^{2} - 0.5

m = \frac{27 π}{200} d^{2} + 0.5
