Cylinders A and B are similar. The length of the cylinder A is 4 mm and the length of cylinder B is 6 mm. The volume of cylinder A is 20mm3. Calculate the volume of cylinder B.
Answer:
67.5
Step-by-step explanation:
Given that :
Cylinder A and cylinder B are similar.
Let volume of cylinder A = 20
We know the volume of a cylinder is given by V =
where, r is the radius of the cylinder
h is the height of the cylinder
We have to find the scale factor.
The length scale factor is =
Area scale factor
∴ Volume scale factor
Therefore, the volume of cylinder B is
= 67.5
