Answer:

12.56

Step-by-step explanation:

The formula for circumference is either πr² πd. Thats basically just multiplying. All you have to do is take the the diameter and multiply it times pi and you get the answer. In some cases they want you to use the radius; radius is diameter divided by 2. Example is if 4 is the diameter 2 is the radius. For this one i did 4 times 3.14(pi).

I hope that helps!

The value of x for each radical equation is 243 , 125,8,256 respectively.

The correct question is attached as an image with the answer.

<h3>What is a Radical Equation ?</h3>

When in an equation the variable is under a radical it is called a Radical Equation.

It is given in the question that

which radical matches to the solution

$\rm \sqrt[5]{x^4} = 81 \\\\\sqrt[3]{x^4} = 625\\\\\sqrt[3]{x^5} = 32\\\\ \sqrt[4]{x^3}=64$

$\rm x^4 = 81^5\\x = 243$

$\rm x^4 = 625^3\\x = 125\\$

$x^5 = 32^3\\x = 8\\$

$\rm x ^3 = 64^4\\x = 256$

Therefore for each radical the value of x is determined.

Find the value of x.<br> (5x +13)<br> (4x+ 2)°<br> (2x -9)

SOVA2 [1]

Answer:

x = 20

Step-by-step explanation:

By exterior angle theorem, we have:

$(4x + 2) \degree + (2x - 9) \degree = (5x + 13) \degree \\ \\(4x + 2 + 2x - 9) \degree = (5x + 13) \degree\\ \\(6x - 7) \degree = (5x + 13) \degree \\ \\ 6x - 7 = 5x + 13 \\ \\ 6x - 5x = 13 + 7 \\ \\ x = 20$

There are 962 souvenir paper weights that need to be packed in boxes. Each box will hold 11 paperweight. How many boxes will be

Naily [24]

You would need 88 boxes. dividing 962 by 11 would lead to 87.45, but the remains cannot just be left out therefore you’d need 88 boxes
