Find the Total surface area of a cone if it's slant height is 21m and diameter of it's base is 24m.

kherson [118]

<h3><u>Answer :- </u></h3>

The total surfAce area of cone is <u>1244.57m².</u>

<h3><u>Step-by-step</u><u> </u><u>explanation</u><u> </u><u>:</u><u>-</u><u> </u></h3>

The total surface area of cone..

<h3><u>Solution :- </u></h3>

Given that ,

The slant height of the cone = 21m.
Diameter of it's base = 24m.

<h3><u>♦</u><u> </u><u>Radius is </u></h3>

<u>=</u>> Diameter / 2

=> 24 / 2

=> 12m

<u>Total surface area of cone = πr ( r + L ) .</u>

<h3><u>Where</u><u> </u><u>we </u><u>know</u><u>,</u></h3>

π = 22/7
r = Radius ( radii )..
L = Slant height.

<h3>According to the question :- </h3>

The total surface of cone is,

<u>=> Total surface area = πr { r + L } ..</u>

$= \frac{22}{7} \times 12 \times (12 + 21)$

$= \frac{22}{7} \times 12 \times 33$

$= (22 \times 12 \times 33) \div 7$

$= (726 \times 12) \div 7$

$= 8712 \div 7$

$= 1244.57 {m}^{2}$

• Therefore , The total surface area of cone is <u>1244.57m².</u>

Hope this helps you :)

Hello, happy Friday, I am just here with some geometry questions.

stealth61 [152]

Answer:

m<D = 105

Step-by-step explanation:

So, Triangle STU and DEF are similar triangles, because their corresponding side lengths have the same ratio.

For example FD can be multiplied by 2.5 to get SU, and EF can be multiplied by 2.5 to get TU, and ED can me multiplied by 2.5 to get 15.

Anyways, since the two triangles are similar, they have the same angle measures, meaning that angle D can be found by subtracting 46 and 25 from 180 degrees to find the missing angle, which is 105 degrees. I hope that helps.

I think of a number double it add 15 my number is 21 what number was i thinking about

AleksandrR [38]

Hello from MrBillDoesMath!

Answer:

Discussion:

Let the number be "n",

2n + 15 = 21 => subtract 15 from both sides

2n = 21 - 15 = 6 => divide both sides by 2

n = 6/2 = 3

Check: Start with 3. Double it (gives 6), add 15 to it ( 6 + 15) which gives 21/

Thank you,

Answer:

There is no solution for given system of inequalities.

Step-by-step explanation:

The system of linear inequalities are given by

$y > \frac{3}{2} x - 1$ ...... (1) and

$y < \frac{3}{2} x - 1$ .......... (2)

The solution of the inequality $y > \frac{3}{2} x - 1$ is shown in the graph by the blue shaded zone and the solution of the inequality $y < \frac{3}{2} x - 1$ is shown in the graph by the red zone.

And it is clear that the solution of the system of inequality equation does not include the line $y = \frac{3}{2} x - 1$

Again, there is no overlap of the blue zone and the red zone so as to indicate solutions for both the inequalities.

Therefore, there is no solution for inequalities (1) and (2). (Answer)
