Question

juanita makes a stack of pennies 38 millimeters tall. each penny has a diameter of 19.05 millimeters.what is the volume of the cylindrical stack of pennies?type the correct answer in the box. use numerals instead of words. round your answer to the nearest cubic millimeter.

Answer 1

10,831 mm^3

Step-by-step explanation:

Cylinder Volume Formula: pi x r^2 x h

radius is equal to the diameter divided by 2. So the radius of the penny stack is 9.525 mm. So that number squared is 90.725625 mm^ 2. Now if you multiply that number by pi you get 285.022... mm^2. Lastly, you multiply that by the height of the objecty which in this case is 38 mm.

38 mm x 285.022... mm^2 = 10,830.9 mm^3
