Answer:
New can holds
more than the old can
Step-by-step explanation:
Given: Diameter of the can is 6 cm and height is 12 cm such that volume of can is 
Dimensions of the can are increased by a multiple of 1.10
To find: Difference between the volume of new can and volume of old can
Solution:
Volume of can (v) = 
Let r, h denote radius and height of the can.
Let R, H denotes radius and height of the new can.
r = diameter/2 = 
h = 12 cm
R = 
H = 
New volume (V) = 
So,
