Answer:

16 times

Step-by-step explanation:

Since the sides are in the same ratio, i.e

1 : 4

The cylinders are similar

(Ratio of sides)² = Ratio of areas

4² = 16

Step-by-step explanation:

Step 1: Make a ratio of the sides

Side of Cylinder A : Side of Cylinder B

1 : 4

Step 2: Find the ratio of the area

$1 : 4$ ← Ratio of Side

$(1)^2 : (4)^2$ ← Ratio of Area

$1 : 16$ ← Ratio of Area

Answer: The area of Cylinder B is 16 times greater than Cylinder A
