A cylindrical piece of metal is 4.5 dm in height with radius of 5.50 x 10^-5 km. a) Calculate the volume in milliliters to the correct significant figures given V=πr^2h for a cylinder.
b) Calculate the volume in mm^3
c) Calculate the density in units g/L to the correct number of significant figures given the metal has a mass of 6.54 x 10^5 grams

a)

b)

c)

Explanation:

Hello,

a) In this case, the given height in cm is:

And the radius in cm is:

Thus, the volume in cubic centimeters which is also equal in mL (1cm³=mL) is:

b) In this case, the given height in mm is:

And the radius in mm is:

Thus, the volume in cubic millimeters is:

c) Finally, since 1000 mL equal 1 L, the required density in g/L turns out:

Best regards.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )
