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}\\\\&#10;A=\pi r^2\quad &#10;\begin{cases}&#10;r=radius\\&#10;-----\\&#10;A=452.16&#10;\end{cases}\implies 452.16=\pi r^2\implies \cfrac{452.16}{\pi }=r^2&#10;\\\\\\&#10;\boxed{\sqrt{\cfrac{452.16}{\pi }}=r}\\\\&#10;-------------------------------\\\\&#10;\textit{circumference of a circle}\\\\&#10;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 "<span>3.1416 as the value of π".</span>

Find the sum of 10 x 2 + 7 x + 6 10x 2 +7x+6 and 6 x + 5 6x+5.
dusya [7]

The sum of the given expression expressed as a quadratic equation is 10x^2 + 13x + 11

<h3>Sum of expressions</h3>

Expressions are equations separated by mathematical signs. This expressions are known to contains certain unknowns

Given the following expression

10x^2 +7x+6 and 6x + 5

We are to take the sum of both expression to have:

f(x) = 10x^2 +7x+6 + 6x + 5

Collect the like terms

f(x) = 10x^2 + 7x + 6x + 6 + 5

f(x) = 10x^2 + 13x + 11

Hence the sum of the given expression expressed as a quadratic equation is 10x^2 + 13x + 11
