Answer:

pi (π)

Step-by-step explanation:

An irrational number has endless non-repeating digits to the right of the decimal point.

Here,

π = 3.14159265359 .........

which doesn't stop or repeat (endless non-repeating digit). That's why pi (π) is a irrational number.

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>Answer :- </h3>

The total surfAce area of cone is 1244.57m².

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

To find :-

The total surface area of cone..

<h3>Solution :- </h3>

Given that ,

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

<h3>♦ Radius is </h3>

=> Diameter / 2

=> 24 / 2

=> 12m

Total surface area of cone = πr ( r + L ) .

<h3>Where we know,</h3>

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

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

The total surface of cone is,

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

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

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

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

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

$= 8712 \div 7$

$= 1244.57 {m}^{2}$

• Therefore , The total surface area of cone is 1244.57m².

Hope this helps you :)

In a class of 28 pupils, if 12 are females. Calculate the ratio of males : total

tensa zangetsu [6.8K]

Answer:

16 : 28

Step-by-step explanation:

If 12 out of the 28 pupils are female, we can calculate the number of males by subtracting the number of females from the total number of pupils.

28 - 12 = 16

So, there are 16 males in the class. Now, we know that the ratio of males : total is 16 : 28.

I hope this helps! Have a lovely day!! :)

A rectangle has a length that is 2 meters more than the width. The area of the rectangle is 288 square meters. Find the dimensio

Rufina [12.5K]

Answer:

L = 18 and w = 16

Step-by-step explanation:

The area of a rectangle is found by A = l*w. Since the length here is 2 more than the width or 2 + w and the width is w, substitute these values and A = 288 to solve for w.

$A = l*w\\288 = w(2+w)\\288 = w^2 + 2w$

To solve for w, move 288 to the other side by subtraction. Then factor and solve.

$w^2 + 2w - 288 = 0 \\(w +18)(w-16) = 0\\$

Set each factor equal to 0 and solve.

w - 16 = 0 so w = 16

w + 18 = 0 so w = -18

Since w is a side length and length/distance cannot be negative, then w = 16 is the width of the rectangle.

This means the length is 16 + 2 = 18.

Solve by using tables. Give each answer to at most two decimal places. –2x2 – 4 = –8x (1 point) 0.59, 3.41 –3.41, –0.59 1.17, 6.

Paul [167]

The answer is ou need to rewrite the equation to make it easy... and let it equal zero 2x2−8x+4=0 which will become 2(x2−4x+2)=0 you need to solve x2−4x+2=0 by completing the square or the general quadratic formula.
