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:
<u>Step 1: Make a ratio of the sides</u>
Side of Cylinder A : Side of Cylinder B
1 : 4
<u>Step 2: Find the ratio of the area</u>
<u />
← Ratio of Side
← Ratio of Area
← Ratio of Area
Answer: The area of Cylinder B is 16 times greater than Cylinder A
