In case of solids, we have volume of the resulting figure = …………… × (volume of the given figure), where k is the scale factor.

1. k

2. k²

3. k³

4. 3k

If scale factor, k = $\dfrac{1}{p}$, then area of the model = …………… × (area of the actual figure).

1. k²

2. k

3. k³

4. $\dfrac{1}{p}$

Assertion (A) : Two circles are always similar.

Reason (R) : Similar shapes have same shape and size.

1. A is true, R is false

2. A is false, R is true

3. Both A and R are true

4. Both A and R are false

Assertion (A) : In a size transformation, if the scale factor k is greater than 1 then it is a reduction.

Reason (R) : Size transformation is a process in which a given figure is reduced by a certain scale factor.

1. A is true, R is false

2. A is false, R is true

3. Both A and R are true

4. Both A and R are false
