Find the circumference of a circle that has an area of 452.16 square meters. (Use 3.1416 as the value of π.)

laila [671]

$\bf \textit{area of a circle}\\\\
A=\pi r^2\quad 
\begin{cases}
r=radius\\
-----\\
A=452.16
\end{cases}\implies 452.16=\pi r^2\implies \cfrac{452.16}{\pi }=r^2
\\\\\\
\boxed{\sqrt{\cfrac{452.16}{\pi }}=r}\\\\
-------------------------------\\\\
\textit{circumference of a circle}\\\\
C=2\pi r\qquad \qquad \implies C=2\pi \left( \boxed{\sqrt{\cfrac{452.16}{\pi }}} \right)$

so, is just that product, recall to use "3.1416 as the value of π".

What are the factors of 3x^2 + 23x − 8?

Margaret [11]

3x² + 23x − 8 = 3x² + 24x - x - 8 = 3x(x+8) - (x+8) = (x+8)(3x-1)

Which expression is equivalent to -0.55 – 0.47a + a?

Leto [7]

Answer:

-0.55 + 0.53a

Step-by-step explanation:

-0.55 – 0.47a + a

To find an expression equivalent to this, we must simplify the equation to a reasonable extent;

-0.55 – 0.47a + a

= -0.55 + 0.53a

= 0.53a - 0.55

The expression equivalent to the given one is -0.55 + 0.53a or 0.53a - 0.55
