Answer:
- The surface area of Cylinder B is 16 times the surface area of Cylinder A
Explanation:
Note: It is assumed we are looking at the total surface area (but the answer would be same for both cases)
Given
- Cylinders A with radius - r, height - h,
- Cylinder B with radius - 4r, height - 4h.
To find
- The ratio of total surface areas of cylinder B to A
Solution
Total surface area of cylinder A is:
Total surface area of cylinder B is:
Find the ratio of areas:
