The head of a nail is circular, as shown. The head of this nail has a diameter of 6 millimeters. Which measurement is closest to
Anastasy [175]

Answer: \boxed{\ 28.26}

My step-by-step explanation:

  1. <u><em>We would use the formula πr2 (pi x radius x radius) </em></u>

<em>     </em><u><em>2.In this problem we were given the diameter of 6, in order to find the radius, you just divide by 2</em></u>

  • <u><em> And so we find:  6mm÷2=3mm </em></u>

   3. So now that we have our radius, we can just plug the numbers into the formula.  So this would be:

  • <u><em>πr2= 3.14 x 3 x 3= 28.26mm2</em></u>

<u><em /></u>

<u><em /></u>

Hope this helps you!

Which is greater 1/9 or 1/8
Sladkaya [172]
1/8 is greater than 1/9 , because 1 is being divided by a smaller number and hence the result would be bigger than when that same 1 is divided by a bigger number as 9.

OR

1/9           1/8            Cross Multiply

8*1            9*1

8                9

8      <        9

Implies that  1/9 is less than 1/8 and hence 1/8 is greater than 1/9.  
 

OR

Use your calculator and convert both to decimal

1/9            1/8

0.111..        0.125

You can see that 1/8 is greater than 1/9.

Find the value of x. x√5=x^4​
Kaylis [27]

Answer:

x=0,\sqrt[6]{5}

Decimal form,

x=0,1.30766048......

Step-by-step explanation:

x\sqrt{5}=x^{4}

x\sqrt{5}-x^{4}=0

(take x as a common factor)

x(\sqrt{5}-x^{3})=0

So,

x=0 and \sqrt{5}-x^{3}=0

for \sqrt{5-x^{3}=0

(add x^{3} for both sides)

\sqrt{5}=x^{3}

x=\sqrt[3]{\sqrt[2]{5} } (multiply 3 by 2)

x=\sqrt[6]{5}

So,

x=0,\sqrt[6]{5}
