I know that D=M/V, so to find M, we would have to multiply D and V, but I was wondering if anyone could check my work:

A cylinder made of tungsten has a radius is 11.0 cm and a length of 25.0 cm. If the density of Tungsten is 19.3 g/cm^3, find the mass of the cylinder in pounds.

So, I started off the equation by finding the volume of the cylinder and I got 9503.317777cm^3
Then I multiplied that by the given density (19.3g/cm^3). That gave me 183,414.0331g.
Afterward, I converted that to lbs and got 404 lbs (I rounded to three significant figures because that was the lowest amount of sig figs in the equation)

Is this answer correct?
And because we are only multiplying and dividing (not adding), I'm supposed to keep all digits and round to the lowest amount of sig figs at the end, correct?

Thank you!

Looks OK.

Since all the numbers have three significant figures, the result should be similar, i.e., rounded up to the 3rd figure. So the mass is 183 kg (kilos) or 183 x 10³ g.

Question doesn't ask for mass in kilograms nor grams.
