Answer:

37 700m² (rounded off to 3 s.f.)

Step-by-step explanation:

When the curved surface area of a cylindrical tank is laid out, it will be like a rectangular piece of sheet with the circumference of the base circle as its length and the height as its breadth.

Circumference of base circle with radius 30cm = pi × 30 × 2

                                                                              = 60pi

2m = 200cm

Curved surface are = 60pi × 200

                                 = 12 000pi

                                 = 37 700m² (rounded off to 3 s.f.)

➡️ 37,680m² will be the curved surface area of the cylindrical tank.

[tex]{\purple{\underline{\textsf{\textbf{Explanation : }}}}}[/tex]

Given that, A cylindrical tank of base radius is 30cm and it's height is 2m or, 200cm

We need to find the curved surface area

We know that,

➩ Curves surface area of a cylinder = 2πrh

r (radius) = 30cm.

h (height) = 200cm.

Therefore,

➩ Curves surface area of a cylinder:

➩ 2 × 3.14 × 30 × 200

➩ 2 × 18,840

➩ 37,680 m² ans.

Answer:

9

Step-by-step explanation:

formula for inverse proportion is y = [tex]\frac{k}{x}[/tex]

k is the constant of probability

to find k,

y is 12, x is 6

12 = [tex]\frac{k}{6}[/tex]

so x = 12 × 6

∴ k is 72

so y = [tex]\frac{72}{8}[/tex]

∴ y is 9

Second rectangle and third rectangle are resulting rectangles scale drawings of one another

The area of Rectangle is length times of width.

Given,

Gayla draws a rectangle.

Second rectangle:

Jared then draws a different rectangle by increasing both the length and the width by 5%.

Third rectangle:

Lyda draws a third rectangle by increasing both the length and the width of Gayla’s by 5 inches.

Let us assume 1 inches as 1 percentage.

So second rectangle and third rectangle are resulting rectangles scale drawings of one another

Hence,  second rectangle and third rectangle are resulting rectangles scale drawings of one another

Complete question :

Ann, Brian and Carol share the cost of a car. Ann pays 2/5 of the cost, Brian pays 1/3 and Carol pays the rest.

a) What fraction of the cost does Carol pay?

b) Ann pays $1600 more than Brian. Find the total cost of the car.

Answer:

4/ 15

8000

Step-by-step explanation:

A)

Fraction carol paid :

Total fraction = 1/1

Fraction paid by Ann and Brian = (2/5 +1/3)

(2/5 + 1/3) = (6 + 5) / 15 = 11/15

1 - 11/ 15 = 4/ 15

Ann = 2/5 ; Brian pays 1/3

Ann pay 1600 more than Brian

2/5 - 1/3 = (6 - 5) = 1/5

1/5 of amount = 1600

If :

1/5 = 1600

1 = x

1/5x = 1600

x = 1600 ÷1/5

Total amount = 8000

What's the question--?

The HCM and LCM of 120 and 180 are 360.

The Highest Common Factor (HCF) of two or more given numbers is the largest number that divides each of the given numbers without leaving any remainder. The Least Common Multiple (LCM) of two or more numbers is the smallest of the common multiples of those numbers.

Given are two numbers as -

120 and 180

We can write 120 and 180 as -

120 = 2 x 2 x 2 x 3 x 5

180 = 2 x 2 x 3 x 3 x 5

HCF of 120 and 180 will be equal to = 2 x 2 x 3 x 5 = 60

Now, we can find LCM using the formula -

LCM(a, b) = (a x b)/HCF(a, b)

LCM(a, b) = (120 x 180)/60

LCM(a, b) = 2 x 180 = 360

Therefore, the HCM and LCM of 120 and 180 are 360.
