Answer:
17662.5 cm2
Step-by-step explanation:
The surface area of a cylinder is given by the following formula:
Surface area = (pi*d^2)/4 + pi*d*h
Where d is the base diameter and h is the height.
Is the diameter and the height are 2.5 times greater, we have that the new surface area is:
New area = pi*(2.5d)^2/4 + pi*2.5d*2.5h = 6.25*pi*d^2/4 + 6.25*pi*d*h = 6.25*(Surface area)
So the larger vase have a area of 6.25 * 2826 = 17662.5 cm2
