If we need to choose the closest answer from the above given ones it is 6471.
SOLUTION:
Diameter(d)= 8
Radius(r)= d/2=8/2 =4,,
Height of cylinder (h)= 12
So,
Volume of cylinder = Pi r^2*h
=22/7 * 4^2 * 12
=4224/7
=603.42,,
The first one is > the the second one is =
14 weeks. 56 divides by 4 to get 14
