Density of zrc is 6.73g/cm. a cylinder of this material has a mass of 56.3 and a length of 12.0. what is the diameter of this object?

ANSWER:
0.94 cm

EXPLANATION

From the question,





This implies that,



But volume is given by the relation;



Substituting equation 2 into equataion 1 and making d the subject.



Multiplying both side of the equation by



gives;



square root both sides gives;



substituting the values of M,V,D and l into equation 4 to get the value for d





Hence the diameter of the object is 0.94 cm

Ok where is the image ?

Ithink is a because if say increased in electronegativity
