The radius and height of cylinder are 14cm and 5m respectively. Find its Surface area

Answer»

ANSWER:

CSA = 44,000 cm²

TSA = 45,232 cm²

Step-by-step explanation:

Given:

  • Radius of cylinder is 14 cm.
  • Height of cylinder is 5 m.

To FIND:

  • Curved Surface Area and Total Surface Area.

Solution: Here Height is in meter and radius is in centimeter so we have to make both units same.

1 m = 100 cm

5 m = 5 x 100 = 500 cm

CSA of cylinder = 2πrh

Putting all values in formula

\small\implies{\sf } CSA = 2 x 22/7 x 14 x 500

\small\implies{\sf } CSA = 44/7 x 7000

\small\implies{\sf } CSA = 308000/7

\small\implies{\sf } CSA = 44,000 cm²

Hence, It's Curved surface area will be 44,000 cm²

TSA of cylinder = 2πr ( h + r )

Putting all values in formula

\small\implies{\sf } TSA = 2 x 22/7 x 14 x ( 500 + 14 )

\small\implies{\sf } TSA = 44/7 x 14 x ( 514 )

\small\implies{\sf } TSA = 616/7 x 514

\small\implies{\sf } TSA = 88 x 514

\small\implies{\sf } TSA = 45,232 cm²

Hence, It's Total Surface area will be 45,232 cm²

Find the amount on Rs 1200 taken for 2 years at 4% p.a. compounded quarterly.​

Answer»

Here, we \:  are  \: given, \\  \\ Principle  \: (P) = 1200 Rs \\ Time \:  (n) = 2 \:  year \\ Rate \:  of \:  Interest  \: (r) =  4\times \frac{1}{100}  =  \frac{4}{100}   \\ Compound  \: Amount  \: (C) = ?

☆ _____________________________________________ ☆

As, we \:  know \:  that, C = P (1+r)^{n} \\  So, C =  1200 \times (1 +  \frac{4}{100} )^{2}  \\ . \:  \:  \:  \:  \:  \:  \:  \:   \: = 1200 \times (1 + 25) ^{2}  \\ . \:  \:  \:   \:  \:  \:  \:  \:  \: = 1200 \times  {26}^{2}  \\ . \:  \:  \:  \:  \:  \:  \:  \:  \:  = 1200 \times 676 \\ . \:  \:  \:  \:  \:  \:  \:  \:  \:  = 811200

Answer: Compound  \: of \:\:  Interest\: \:  is \:  811200  \: Rs.

if an arithmetic progression if p times of pth term equal to q times of qth term then show that the p+q th term is equal to zero​

Answer»

Let a be the first TERM and d be the COMMON difference of the given A.P.

Given: (p times pth term)  = (q times QTH term)

p ap = q aq

p{ a + (p-1) d } = q { a + ( q - 1 ) d }

ap + p²d - pd = aq + q²d - qd

ap - aq = - p²d + q²d - qd + pd

a (p - q ) = d ( q² - p² + p - q )

a ( p - q ) = d { ( q - p ) ( q + p) + p - q }

[ a² - b² = (a+b)(a-b)]

a ( p - q ) = d ( p - q ) { -1 ( p + q) + 1 }

a = d ( - p - q + 1 ) ……………..(1)

( p + q )th term = a + (n - 1 ) d

here , n = (p+q)

(p + q)th = a + ( p + q  - 1 ) d ………….(2)

substituting a = d ( - p - q + 1 ) in eq. ( 2 )

(p + q)th = d (- q - p + 1 ) + ( p + q - 1 ) d

= -DP - dq + d + pd + qd - d

(p + q)th = 0

Hence, (p + q)th term of an A.P is zero.

Solve simultaneous equation for equation x and ym+(x+y)+ n(x-y)-(m²+mn+n²)=0n(x+y)+m(x-y)-(m²-mn+n²)=0

Answer»

The simultaneous equations are

m(x+y) +n(x-y)-(m²+MN+n²) =0 and

n(x+y) +m(x-y)-(m²-mn+n²) =0.

We have to solve those two equations for x and y.

Now, m(x+y) +n(x-y)-(m²+mn+n²) =0

⇒ x(m + n) + y(m - n) = m² + mn + n² ........... (1)

And, n(x+y) +m(x-y)-(m²-mn+n²) =0

⇒ x(m + n) - y(m - n) = m² - mn + n² ........... (2)

Now, eliminating y from equations (1) and (2) we get,

2x(m + n) = 2(m² + n²)

⇒ (Answer)

Similarly, eliminating x from equations (1) and (2) we get,

2y(m - n) = 2mn

⇒ (Answer)

Answer»

ANSWER:

The capacity of a cubical tank of side 1 m in litres is 1000 liters

Step-by-step explanation:

Length of edge of cubical tank = 1 m

VOLUME of tank = Side^3

Volume of tank =1^3 = 1 m^3

1 m^3 = 1000 liters

So, The volume of cubical tank = 1000 liters

Hence the capacity of a cubical tank of side 1 m in litres is 1000 liters

or

cub8cal tank side= 1m

voluke of CUBE = (side)^3

= (1)^3 m^3

= 1 liter

Answer»

Step-by-step explanation:

Homemaking is a mainly AMERICAN term for the management of a HOME, OTHERWISE known as housework, housekeeping, or household management. It is the act of overseeing the organizational, day-to-day operations of a house or estate, and the managing of other domestic concerns. A person in charge of the homemaking, who is not employed outside the home, in the United States is called a homemaker, a term for a housewife or a househusband. The term "homemaker", however, may also refer to a social worker who manages a household during the incapacity of the housewife or househusband.[1]

Housework is not always a LIFETIME commitment; many, for economic or personal reasons, return to the workplace. In previous decades, there were a number of mandatory courses for the young to learn the skills of homemaking. In high school, courses included cooking, nutrition, home economics, family and consumer science (FACS), and food and cooking hygiene. More recently, most of these courses have been abolished, and many youths in high school and college would likely study CHILD development and the management of children's behavior.
