Answer: 10pi

Step-by-step explanation:

C=2*pi*r

C=2*pi*5

C=10*pi (exact)

This is exact if u want numbers, you’ll have to round-off and you can just put 10xpi into a calculator If u want to see.

C = 2 π r

C = 2 · π · 5

C = 31.41593

One solution of x^2-25=0 is 5 what is the other solution
zepelin [54]

Add 25 to both sides:


x^2 = 25


Square root both sides.


When you square root a perfect square, you will get a plus/minus result:


\sqrt{25} = \pm 5


x = \pm 5

\boxed{x = -5} \land \boxed{x = 5}


The other solution to this answer is x = -5.

Citrus2011 [14]

Answer:

As per the statement: A radio station had 205 tickets to a concert. They gave away 4 times as many tickets to listeners as to employees.

⇒Let number of tickets Employees have x and Number of ticket Listeners  have 4x

It is also, given that a radio station had 205 ticket to a concert.

⇒ \text{Number of ticket Employees have} +\text{Number of ticket Listeners have} = 205

Then, substitute the given values we have;

4x + x = 205

Combine like terms, we have;

5x = 205

Divide both sides by 5 we have;

x = 41

Therefore, number of tickets did they give away to employees have 41 tickets
