Now

volume:-

Answer:

Step-by-step explanation:

In the question we are given ,

And we are asked to find the volume of cone. We know that ,

[tex] \red{\boxed{ \rm{Volume \: of \: cone = \frac{1}{3} \pi r {}^{2}h }}}[/tex]

Where ,

So , for finding volume of cone we must have to find the height of cone using slant height formula i.e. ,

[tex] \green{\boxed{ \sf{l {}^{2} = h {}^{2} + r {}^{2} }}}[/tex]

Where ,

Now , substituting values :

[tex] \hookrightarrow \: 7.5 {}^{2} = h {}^{2} + 4.5 {}^{2} [/tex]

Transposing 4.5 to left hand side :

[tex] \hookrightarrow \: 7.5 {}^{2} - 4.5 {}^{2} = h {}^{2} [/tex]

[tex] \hookrightarrow \:56.25 - 20.25 = h {}^{2} [/tex]

On further calculations we get :

[tex] \hookrightarrow \:h {}^{2} = 36[/tex]

[tex] \hookrightarrow \:h = \sqrt{36} [/tex]

We know that 6 × 6 is equal to 36 that means square root of 36 is 6 . So :

[tex] \hookrightarrow \pink{\boxed{\bold{h = 6 \: cm}}}[/tex]

Substituting values in volume formula :

[tex] \longrightarrow\: \frac{1}{ \cancel{3} } \times 3.14 \times (4.5) {}^{2} \times \cancel{6}[/tex]

Step 1 : By cancelling 6 with 3 we get :

[tex] \longrightarrow \: 3.14 \times 20.25 \times 2[/tex]

Step 2 : Multiplying 20.25 with 2 :

[tex] \longrightarrow \:3.14 \times 40.50[/tex]

Step 3 : Multiplying 3.14 with 40.50 :

[tex] \longrightarrow \: \purple{\boxed{\bold{127.17 \: cm {}^{3} }}}[/tex]

Answer:

5 = |-5|

Step-by-step explanation:

Think of it as a number line, like in the picture below. The absolute value is how far a number is from zero (0). If 5 is 5 away from zero, then the opposite of 5 (-5) is also 5 away from zero.

Refer to the picture below for an illustration:

Answer:

Equal to.

Step-by-step explanation:

5 is the absolute value of -5. The bars you see indicate that you are trying to find the absolute value.

----------------------------------------------------------------------------------------------------------

The absolute value is the distance of that number from 0. The absolute value is always positive.

----------------------------------------------------------------------------------------------------------

|-5|= 5. If the bars were not there, then it would be [tex]5 > -5\\[/tex]. If the two terms were flipped, it would be [tex]-5 < 5[/tex]. But because the bars are there, it is resembling the absolute value.

----------------------------------------------------------------------------------------------------------

Here are a few more examples to help you understand:

|6| The absolute value of 6 is 6. It is 6 values away from 0.

|-1| The absolute value of -1 is 1. It is 1 value away from 0.

|-10| The absolute value of -10 is 10. It is 10 values away from 0.

|98| The absolute value of 98 is 98. It is 98 values away from 0.

Answer:

1.2 cm

Step-by-step explanation:

3/5, in decimal form, is 0.6.

You find the diameter by multiplying the radius by 2.

0.6 * 2 = 1.2

Answer:

1 1/5 or 1.2

Step-by-step explanation:

You multiply the radius (the number in the picture) by two, because the diameter is twice the radius

Answer:

incorrect, correct answer is 4√2

Step-by-step explanation:

When you remove the square root You will have to remove them completely. so that the inside of the square root cannot be removed any more numbers (I'm not good at English but I hope u understand what I want u to know :)))

√32 = √2×2×2×2×2

Match 2 identical numbers one at a time and bring them out. ;

√32 = 2×2√2

√32 = 4√2 correct answer!

find you If you want to check if your square root removal is correct or not. Multiply the answer you have given by itself, for example:

4√2 × 4√2 = 16×√4 = 16×2 = 32 correct!

hope it helps you <3

She had taken 2 outside without consideration of square root. And the correct value of √32 is 4√2.

If the value of a numerical expression is terminating then they are the rational number then they are called the rational number and if the value of a numerical expression is non-terminating then they are called an irrational number.

Jaclyn estimates the square root of 32 in the following way:

√32 = 2√16 = 2 ∗ 4 = 8

a)  She had taken 2 outside without consideration of square root.

b)  The √32 is correctly solved below.

[tex]\sqrt{32} = \sqrt{2*2*2*2*2} = 2*2*\sqrt2=4\sqrt2[/tex]

Then the correct value of √32 is 4√2.
