Question

i need help!!!

Answer 1

Aubrey,

 

Volume of the can is pi*r^2*h = pi*4*4*12 = 603.18 cu cm

 

Meatballs take 42% volume, which is 0.42*603.18 = 253.34 cu. cm

 

Volume of each meatball = (4/3)*pi*r^3 = (4/3)*pi*1.72^3 = 21.31 cu. cm

 

Number of meatballs = 253.34/21.31 = 11.88 or 11 meatballs
