The area of the surface of a circular pond is needed. A measure about the pond gives a circumference of about 47 feet. Find the
Whitepunk [10]

Answer:

55.95 ft²

Step-by-step explanation:

Circumference formula:  C = 2πr  =>  r = C / (2π)

Area formula:  A = πr²

Substituting C / (2π) for r in the above equation, we get:

               C                        47 ft

A = π( ----------- )²  =  π ( -------------- )²

              2π                       (2π)

or ...

          π(47 ft)²                   2209 ft²

A = ----------------------  =  --------------------  =  55.95 ft²

               4π²                   4(3.14159)²

For what value of x would the expression below be undefined? 2x − 15 x + 9
Naddik [55]
Hey there!

I'm assuming your expression is actually \frac{2x - 15}{x + 9}. If it's not, let me know and I'll be happy to help you out further. 

If x were equal to –9, your expression would be undefined. If you solve it with this value plugged in for x, you will get the following: 

\frac{2x - 15}{x + 9}

\frac{2(-9) - 15}{(-9) + 9}

\frac{-18 - 15}{0}

\frac{-33}{0}

error

You can't divide anything by zero. This expression would be undefined if x were –9 since it makes the denominator zero. Therefore, x ≠ –9. 

Hope this helped you out! :-)
