**Solved Questions For You:**

**Question 1.Â Find the rate of change of the area of a circle with respect to its radiusÂ $r$Â when**

**(i)Â $r=3$Â cm**

**(ii)Â $r=4$Â cm**

**A.Â 6Ï€,Â 8Ï€**

**B.Â 5Ï€,8Ï€**

**C.Â 4Ï€,10Ï€**

**D.Â 2Ï€,8Ï€**

**Answer:Â**

$A=Ï€r2$

**Question 2.Â ****LetÂ $f:Râ†’R$Â be defined asÂ $f(x)=3x$. Choose the correct answer.**

**A.Â $f$Â is one-one onto**

**B.Â $f$Â is many-one onto**

**C.Â $f$Â is one-one but not onto**

**D.Â $f$Â is neither one-one nor onto**

**Answer:**

$f:Râ†’R$Â is defined asÂ $f(x)=3x$.

LetÂ $x,yÂâˆˆÂR$Â such thatÂ $f(x)=f(y)$

$â‡’3x=3y$

$â‡’x=y$

$âˆ´f$Â is one-one

Also, for any real numberÂ $(y)$Â in co-domianÂ $R$,

there exists \(\frac{y}{3}\)Â Â inÂ $R$Â such that

$f(\(\frac{y}{3}\))Â=3(\(\frac{y}{3}\))=y$

$âˆ´f$Â is onto.

Hence, functionÂ $f$Â is one-one and onto

The correct answer isÂ $A$.

**Question 3: Give an example of a relation. Which isÂ Reflexive and symmetric but not transitive.**

**Answer:**

LetÂ $A={4,6,8}$

$A={(4,4),(6,6),(8,8),(4,6),(6,4),(6,8),(8,6)}$

RelationÂ $R$Â is reflexive since for everyÂ ${aâˆˆA,(a,a)âˆˆRi.e.,(4,4),(6,6),(8,8)}âˆˆR$

$a,bâˆˆR$.

RelationÂ $R$Â is not transitive sinceÂ $(4,6),(6,8)âˆˆR$, butÂ $(4,8) \(\notin\)ÂR$.

**Question 4: LetÂ $R$Â be the relation in the setÂ ${1,2,3,4}$Â given byÂ $R={(1,2),(2,2),(1,1),(4,4),(1,3),(3,3),(3,2)}$.Â **

**Choose the correct answer.**

**A.Â $R$Â is reflexive and symmetric but not transitive.**

**B.Â $R$Â is reflexive and transitive but not symmetric.**

**C.Â $R$Â is symmetric and transitive but not reflexive.**

**D.Â $R$Â is an equivalence relation.**

**Answer:**

It is seen thatÂ $(a,a)âˆˆR$, for everyÂ $aâˆˆ{1,2,3,4}$.

$âˆ´$Â $R$Â is reflexive.

It is seen thatÂ $(1,2)âˆˆR$, butÂ $(2,1) \(\notin\)ÂR$.

$âˆ´$Â $R$Â is not symmetric.

Also, it is observed thatÂ $(a,b),(b,c)âˆˆRâ‡’(a,c)âˆˆR$Â for allÂ $a,b,câˆˆ{1,2,3,4}$

$âˆ´$Â $R$Â is transitive.

Hence,$R$Â is reflexive and transitive but not symmetric.

The correct answer is B.
