A sample of gold weighs 100 grams and has a volume of 5.18 cm'. What is the density of gold?

19.31 g/cm^3... I’m assuming when you said cm’ you meant cm^3

A chord is a line which touches two points on the circle where as diameter is a line which touches two points on the circle but passes through the center of a circle so diameter can be alse called chord but chord can not be called diameter because it doesnot pass through center.so right option is C. A diameter is always a chord.
