6.	The internal and external diameters of a metallic pipe are 44 cm and 46 cm resptly. The pipe is painted from outside and inside. The total cost of painting at the rate of rs.2.50 per square metre is rs.99. Caculate the length of the pipe
Answer» N, Inner radius(r)=2cm Outer diameter(D)=4.4cm Length of metal pipe=77cm If outer sphere diameter =4.4cm, then, it's radius= 2 4.4 ∴ Outer sphere radius(R)=2.2cm Now, let US find inner CURVED surface area=? As we know that, Surface area of a sphere =2πrh sq.cm where, π= 7 22 ,r=2cm,h=77cm ∴ Inner curved surface area=2× 7 22 ×2×77 =44×22 sq. cm =968 sq. cm ∴ Inner curved surface area(s 1 )=968 sq.cm Now, let us find outer curved surface area, as, we know that, Surface area of outer sphere=2πRh sq. cm where, π= 7 22 , R=2.2cm, h=77cm so, we get, Outer curved surface area=2× 7 22 ×2.2×77cm 2 =22×2×2.2×11cm 2 =44×2.2×11cm 2 =1064.8 sq.cm ∴ Outer curved surface area(s 2 )=1064.8 sq. cm Now let us find total surface area as, we know that, Total surface area = Inner surface area (s 1 )+Outer surface area (s 2 ) T.S.A=[968+1064.8]sq. cm ⇒ T.S.A=2,032.8 sq.cm ∴ Total surface area(s)=2032.8cm 2 .

The internal and external diameters of a metallic pipe are 44 cm and 46 cm resptly. The pipe is painted from outside and inside. The total cost of painting at the rate of rs.2.50 per square metre is rs.99. Caculate the length of the pipe

Answer» N,

Inner radius(r)=2cm

Outer diameter(D)=4.4cm

Length of metal pipe=77cm

If outer sphere diameter =4.4cm, then, it's radius=

2

4.4

∴ Outer sphere radius(R)=2.2cm

Now, let US find inner CURVED surface area=?

As we know that,

Surface area of a sphere =2πrh sq.cm

where, π=

22

,r=2cm,h=77cm

∴ Inner curved surface area=2×

7

22

×2×77

=44×22 sq. cm

=968 sq. cm

∴ Inner curved surface area(s

)=968 sq.cm

Now, let us find outer curved surface area, as, we know that,

Surface area of outer sphere=2πRh sq. cm

where, π=

7

22

, R=2.2cm, h=77cm

so, we get,

Outer curved surface area=2×

22

×2.2×77cm

=22×2×2.2×11cm

2

=44×2.2×11cm

2

=1064.8 sq.cm

∴ Outer curved surface area(s

2

)=1064.8 sq. cm

Now let us find total surface area as, we know that,

Total surface area = Inner surface area (s

1

)+Outer surface area (s

2

)

T.S.A=[968+1064.8]sq. cm

⇒ T.S.A=2,032.8 sq.cm

∴ Total surface area(s)=2032.8cm

Answer» ONG>Answer: Step-by-step explanation: The train is 50 km south -west of its starting POINT You NEED to draw the lines or the diagram as the direction of train. So, now as train goes 120km in west ,30 km in south and again 80 km in east direction, connect the points from where it starts to where it ends. You will get a right angle triangle so now we know two sides of that triangle i.e. 30km and 40 km. So, now using Pythagoras theorem we get distance as 50KM south-west.

Answer»

ong>Step-by-step EXPLANATION:

By cross MULTIPLICATION, do you mean cross multiplication of the coefficients of the variables?

xa+yb=2

ax−by=a2−b2

Rewrite the first equation in a more BEAUTIFUL form. Multiply it throughout by ab .

bx+ay=2ab

The coefficients of the variables are interchanged between the two equations. I assume that by cross multiplication, you mean making the coefficients equal, so that a simple subtraction of the equations will eliminate a variable.

Multiply the first equation by a and the second by B .

abx+a2y=2a2b

abx−b2y=a2b−b3

Subtract them.

(a2+b2)y=(a2+b2)b

⟹y=b

Substituting this value in any of the above equations will yield the value of X .

bx+ay=2ab

Give a gemetorical representation of 3x+12=0 as an equation in one variable

Answer»

ong>Answer:

Answer and explanation:

Given : Geometric equation 3x+12=03x+12=0

To FIND : Represent equation in

(1) in one variable

(2) in two variables

Solution :

In one variable, 3x+12=03x+12=0 is a point (-4,0).

In two variables, we have x and y axis.

So, writing equation 3x+12=03x+12=0 in terms of x and y.

3x+12=03x+12=0

0+3x+12=00+3x+12=0

0y+3x+12=00y+3x+12=0 .....(1)

Put y=0 in (1),

0(0)+3x+12=00(0)+3x+12=0

3x=-123x=−12

x=-4x=−4

Put y=1 in (1),

0(1)+3x+12=00(1)+3x+12=0

3x=-123x=−12

x=-4x=−4

So, Points are (-4,0) and (0,-4)

In two variables, 3x+12=03x+12=0 is line which is PARALLEL to y-axis.

If sx =(3x^2+2x), find the first term and common difrence of the ap

Answer»

$\underline{\textsf{Given:}}$

$\textsf{Sum of first x terms of an A.P}$

$\mathsf{S_x=3x^2+2x}$

$\underline{\textsf{To <klux>FIND</klux>:}}$

$\textsf{First term and common ratio}$

$\underline{\textsf{Solution:}}$

$\textsf{Consider,}$

$\mathsf{S_x=3x^2+2x}$

$\textsf{For x=1,}$

$\mathsf{S_1=3(1)^2+2(1)}$

$\implies\mathsf{a=3+2}$

$\implies\boxed{\mathsf{a=5}}$

$\textsf{For x=2,}$

$\mathsf{S_2=3(2)^2+2(2)}$

$\implies\mathsf{a+(a+d)=12+4}$

$\implies\mathsf{2a+d=16}$

$\implies\mathsf{2(5)+d=16}$

$\implies\mathsf{10+d=16}$

$\implies\boxed{\mathsf{d=6}}$
