A sphere with surface area of 154cm² is fit exactly in cubical box, Use π 22/7

Mathematics

Answer:

<h2><u>Answer</u><u> </u><u>:</u><u>-</u></h2>

Surface area of sphere = 4 π r²

154 = 4 × 22/7 × r²

154 = 88/7 × r²

154 × 7/88 = r²

12.25 = r²

3.5 = r

Now

Volume of sphere = 4/3 × π r³

Volume = 4/3 × 22/7 × (3.5)³

Volume = 88/21 × 42.875

Volume = 154 cm³

Volume of sphere = Volume of cube

Volume of cube = 154 cm³

Anyone know how to simplify a whole number into a mixed number or a improper fraction???
AlekseyPX

Answer:

Example any whole number over one would be an improper fraction, so 2=2/1, something like 5/3=1 2/3 would be a mixed number, subtract the numerator by the denominator, how ever many times you can subtract is the whole number and the amount remaining is the numerator, keep the same denominator,,, hope that makes sense

How can I do this exercise? <img src="https://tex.z-dn.net/?f=%5Cfrac%7B-2%7D%7B12%7D%20%3D%20%5Cfrac%7Bx%20%2B%201%7D%7Bx%20%2B

Answer:

-8/7 =x

Step-by-step explanation:

-2         x+1

----- = -----------

12         x+2

Using cross products

-2 (x+2) = 12 (x+1)

Distribute

-2x -4 = 12x+12

Add 2x to each side

-2x+2x -4 = 12x+2x+12

-4 = 14x +12

Subtract 12 from each side

-4-12 = 14x

-16 = 14x

Divide each side by 14

-16/14 =14x/14

-8/7 =x

Ashley digs 7 holes.She puts 2 seeds in each hole.She has 3 seeds left over.How many seeds are there in all?
Semenov [28]
17 seeds are left over because in the 7 holes she puts 2 seeds in each which if you multiply it it will equal to 14 and plus the three that she has left over and if you add 14 and 3 you get 17 seeds. hope this helps!

How do i solve this step by step
AlladinOne [14]

Answer:

4) x^10

Step-by-step explanation:

1) If two numbers have the same base (i.e. x^3 and x^4) and you are multiplying them you just add the exponents. Therefore x^3*x^4 would be x^(3+4) which equals x^7.

2) When dividing similar bases you have to subtract the exponents. If we have x^18÷x^8 that is equivalent to x^(18-8) which gives us x^10.

3) If we have (x^3)^3 we will need to multiply the exponents. Therefore (x^3)^3 is equivalent to x^(3*3) which gives us x^9.

4) (x^2*x^4)^4÷x^8

First do what's in the parentheses,

(x^2*x^4) = x^6

Next do the exponents,

(x^6)^3 = x^18

Lastly the division,

x^18÷x^8 = x^10

x^10 is our answer.
