Mr. Monopoly, my ass! What happened to rich Uncle Pennybags?

flowbark has a small cylinder that he has filled with 50 pennies. It is 7mm tall and has a radius of 39mm.

flowbark also has a small pennybag (ok, it’s a laundry bag) that has a 130mm radius and 320mm height.

Q1: How many pennies will fit into flowbark’s pennybag?

Q2: How much will the pennybag weigh?

The volume of a cylinder is piradius-squaredheight.

S= Volume of small cylinder: 6004
PB= Volume of pennybag: 16,989,733

Number of pennies that fit into pennybag = 50*(PB/S)= 141,486

Rich Uncle Pennybags carries around $1,414.86 in spare change. (This does not include his extensive interests on the Boardwalk and on Park Place).

50 pennies weigh about 4 1/2 ounces. 141,486 pennies weigh about 800 pounds. That’s one strong Uncle.
