2. A Cylindrical hot water tank is closed at both ends. The radius of the tank is 0.5m and the height is 0.75.calculate i. The volume of the Cylinder it. The total surface area of the tank (take π =22 out of 7​

Answers

Answer 1

Answer:

Volume = 0.59 m³

Surface Area = 3.93 m²

Step-by-step explanation:

Given :-

- Radius = 0.5 cm

- Height = 0.75 cm

To Find :-

- Volume

- Surface Area

Solving :-

Volume = πr²h

= 22/7 x (0.5)² x 0.75

= 22/7 x 1/4 x 3/4

= 66/112

= 33/56 m³

= 0.59 m³

Surface Area = 2πr (r + h)

= 2 x 22/7 x 0.5 (0.5 + 0.75)

= 22/7 x 5/4

= 110/28

= 55/14 m²

= 3.93 m²

Solution :-

Volume = 0.59 m³

Surface Area = 3.93 m²

Answer 2

Answer:

1. Formula for volume of a cylinder;

V = πr^2h

where pi is 3.14 or 22/7, r is the radius(0.5) which is squared, and h is the height

plug in the actual values;

V = πr^2h

V = 3.14 * 0.5^2 * 0.75

V = 3.14 * 0.25 * 0.75

V = 0.785 x 0.75

V = 0.58875^3 meters or 0.59^3 meters, is the volume. (round to whatever place they covet)

2. Formula for surface area of a cylinder;

SA = 2πr(r + h)

Plug in the actual values:

SA = 2πr(r + h)

SA = 2 x 3.14 x 0.5(0.5 + 0.75)

SA = 2 x 3.14 x 0.5(1.25)

SA = 2 x 3.14 x 0.625

SA = 3.925 meters or 3.93 meters is the surface area.

2)(3x-0)=9

Step-by-step explanation:

The property used for the expression (5x-10)(-2x+-10)=9 is distributive.


What is distributive property?

This property states that multiplying the sum of two or more addends by a number produces the same result as multiplying each addend separately by the number and then adding the products together.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the step is 5(x-2) -2(x-5)=9. The step will be solved by the distributive property. By multiplying the two parts with each other and simplifying them.

The conic section which is represented by the provide equation is the equation of ellipse and represent ellipse conic section.

How to identify the type of conic section from an equation?

To of identify the type of conic section from an equation whether it is circle, or ellipse a let suppose the equation as,

[tex]Ax^2+By^2+Cx+Dy+E=0[/tex]

In this equation, if,

[tex]A\neq B[/tex]

Then it is the equation of circle.

If In this equation,

[tex]A\neq B[/tex]

But both A and B has same sign (either positive or negative) then it is the equation of ellipse.

The given equation in the problem is,

[tex]3x^2 - 7x+ 8y^2 - 2y+ 1 = 0[/tex]

Here, in the equation,

[tex]A=3\\B=8[/tex]

The A is not equal to B but the sign of both are positive. Hence this equation is the equation of ellipse.

what is the point slope form of (-7,5) , (1,-1)​

Answers

Answer:

y-5=-2/3(x-(-7))

Step-by-step explanation:

I just learned this recently as well so bare with me.

So the point slope form is y-y1=m(x-x1)

So first we have to find the slope. So we do 5-(-1)/-7-1=-6/8=-3/4

So now, we just have to plug in the numbers.

So y-5=-2/3(x-(-7)).

I know that looks a little funky but if you used the slope intercept form, you would get the same answer if you just simplified this version. Of course, you don't have to simplify this version because this version is completely acceptable.

The area of a circle is πr², where r = radius. We're given the radius as 8 millimeters, and we're going to approximate pi as 3.14.

Solving

3.14 × 8²3.14 × 64200.96

Therefore, the area is 200.96 millimeters².

Have a lovely rest of your day/night, and good luck with your assignments! ♡

We know that:

Radius = 8 mmArea of circle = πr²

Finding the area of the circle.

Area of circle = πr²=> Area of circle = 3.14 x 8²=> Area of circle = 3.14 x 64=> Area of circle = 200.96 mm²

2x + 3/5 = 5.6x (Simplify both sides of the equation)

2x + 3/5 - 5.6x = 5.6x - 5.6x (Subtract 5.6x from both sides)

-3.6x + 3/5 = 0

-3.6x + 3/5 - 3/5 = 0 - 3/5 (Subtract 3/5 from both sides)
