and are mathematically similar cylinders. Cylinder has surface area and Cylinder has surface area . If Cylinder has volume , find the volume of Cylinder .
Answer and explanation
Correct answer: A.
- Step 1: Find the area scale factor and linear scale factor: area scale factor . Therefore the linear scale factor is .
- Step 2: Find the volume scale factor: .
- Step 3: Multiply the volume of Cylinder by the volume scale factor: .
Answer
.
Why not the others: incorrectly multiplies volume by the area scale factor (); multiplies by the linear scale factor squared; multiplies by an unscaled power.
