Answer»

Answer:

4950 juice BOTTLE can be filled up in 22 hours and 3 hours is required to fill up 2700 bottles

Step-by-step explanation:

First part

No. of juice bottles filled up in 4 hours: 900

No. of juice bottles filled up in 1 hour: 900/4

                                                             = 225

No. of juice bottles filled up in 22 hours: 225*22

                                                                    =4950

Second part

Time required to fill up 900 bottles: 4 HRS

Time required to fill up 1 bottle: 4/900

Time required to fill up 2700 bottles: 4/900 * 2700

                                                              =3 hrs

The height of a cone is 14 cm and the area of its base is 321 cm square. Find the volume. ​​

Answer»

Answer:

v = 1496 cm^3

Step-by-step explanation:

HEIGHT: 14 cm

Area of base: 321 cm^2

Volume of CONE= (1/3)πr^2h

Area of base:  πr^2

π = (22/7) (in this cause we will SET PI = 22/7)

we just need to find the radius to plug it in to the volume formula

πr^2 = 321 cm^2

(22/7)r^2 *(7/22)*(321cm^2)

r = (102cm^2) ^ (1/2)

r = 10.995..cm

r = 10.10 cm

Volume = (1/3)πr^2h

h = 14 cm

r = 10.10 cm

v = (1/3)π(10.10cm)^2(14 cm)

v = 1496 cm^3

The total surface area of a hollow cylinder which is open from both sides is 4620 sq.cm, area of base ring is 115.5 sq.cm and height 7 cm. Find the thickness of the cylinder.​

Answer»

ANSWER:

Total surface area of cylinder = 3575 cm2

Area of the BASE ring = 357.5 cm2

Height = 14 cm

Let us consider

The inner radius = r

OUTER radius = R

Area of the base ring

π(R2−r2) = 357.5 cm2

R2−r2 = 357.5/π

Value of π = 22/7 = 3.143

R2−r2 = 357.5/3.143

R2−r2 = 113.74 sq.cm

(R + r)(R – r) = 113.74 sq.cm…………………….(1)

Total surface area of a hollow cylinder = outer curved surface + inner curved surface area + 2(Area of the circular base)

3575 = 2πRh + 2πrh + 2π (R2−r2)

3575 = 2πRh+2πrh+ 2 × 357.5

3575 = 2πh(R+r) + 715

2πh(R+r) = 3575 – 715

2πh(R+r) = 2860

(R + r) = 2860/(2 × 3.143 × 14)

(R + r) = 2860/88.004

(R + r) = 32.498…………………………….(2)

Substitute the value of equation (2) in equation (1) we get

(32.498) × (R – r) = 113.74

(R – r) = 3.49 cm

The THICKNESS of the cylinder is 3.49 cm.

In the figure, find the values of x and y. Is triangle ABC isosceles? If so name the equal sides.​

Answer»

x + 115 = 180 (LINEAR angles)
x = 180 - 115
x = 65

x+y+50=180 ( ANGLE sum property )
65+y+50=180
y+115=180
y=180-115
y=65

Since x=y we can SAY that triangle ABC is isocèles,
AB=AC ( isocèles property )

The length, BREADTH and height of a room are 18CM, 15cm and 12CM RESPECTIVELY. it

has 2 DOORS each 6m by 3m and 3 windows each 4m by 2m. Find the cost of white

washing its wall at 75 paisa per square metre.

\huge{\mid{\fbox{\tt{αղsաҽɾ}}\mid}}

⇛It is given that length, breadth and height of a room are 8 m, 5 m and 3 m respectively.

⇛Area of four walls of the room is: 2h(l+b)

⇛A=2h(l+b)=2×3(8+5)=6×13=78 m2

⇛Area of the ceiling is: A=l×b=8×5=40 m 2

⇛Total area of the four walls and the ceiling of the room is 78+40=118 m2

⇛It is given that cost of white washing is Rs.15/m

2, therefore,

⇛Total cost of white washing is: 118×15=1770

\: Hence, \: the \: cost \: of \: \\ white \: washing \: the \: \\ walls \: is \: Rs.1770. \\
