To compare the surface areas of the two soda cans, we first need to calculate the surface area of each can.
The formula for the surface area of a cylinder is:
Surface Area = 2Ï€r^2 + 2Ï€rh
Where r is the radius of the base of the cylinder and h is the height of the cylinder.
For Can A:
Radius = / 2 =
Height =
Surface Area A = 2Ï€(2.5)^2 + 2Ï€(2.5)(5)
Surface Area A = 2Ï€(6.25) + 2Ï€(12.5)
Surface Area A = 12.5Ï€ + 25Ï€
Surface Area A = 37.5Ï€ square units
For Can B:
Radius = / 2 =
Height =
Surface Area B = 2Ï€(3)^2 + 2Ï€(3)(4)
Surface Area B = 2Ï€(9) + 2Ï€(12)
Surface Area B = 18Ï€ + 24Ï€
Surface Area B = 42Ï€ square units
Now we compare the surface areas:
Surface Area A = 37.5Ï€
Surface Area B = 42Ï€
Can B has a greater surface area than Can A by:
42Ï€ - 37.5Ï€ = 4.5Ï€ square units
So, Can B has a greater surface area by 4.5Ï€ square units.
