3. The multiplicative inverse of 1010 is………………
4. Volume of a cylinder with radius r and height h is ………..
5.The percentage of 2: 3 is ………..
6. …………….. is a regular quadrilateral.
7. The diagonal of the square are ……………..
8. After 18 yr, Saurabh will be 4 times as old as he is now. His present age is……………..

Answer 1

Answer:

${ \huge{ \red{ \sf{Solution:}}}}$

1. Polynomial.

Because if multiply two polynomials we get again polynomial only.

Eg:- x + 2 × (x + 3) = x² + 2x +3x + 6 = x² + 5x +6

2. x/y = k

3. 1/1010

4. πr²h

5. 2/3 × 100 = 66.66%

6. Square is a regular quadrilateral

7. Equal

8. 6 years

Let saurabh age is x

After 18 years his age is ( x + 18 )

From question,

x + 18 = 4x

x - 4x = -18

3x = 18

x = 6

Answer 2

Answer:

1. polynomial

2. x/y.

3. -415.

4. V = πr^2h.

5. (2:3)% = 2/3 × 100

= 66.66%.

6. Square.

7. Two.

8. 6 years.
