Estimate the circumference of a circle that has a radius of 11 m simplify it.

Zanzabum

ANSWER

$C=22\pi \: m$

EXPLANATION

The circumference of a circle is calculated using the formula:

$C=2\pi \: r$

where r=11 meters is the radius of the circle.

Let us substitute the radius into the formula to obtain,

$C=2\pi \: \times 11$

This simplifies to:

$C=22\pi$

When we substitute

$\pi = 3.14$

We get

$C=22(3.14) = 69.08m$

to the nearest hundredth.

Hank’s teacher asked him to verify that the product (y – 3)(y2 + 3y + 9) is a difference of cubes. He used the distributive prop

kicyunya [14]

Answer:

a = 9

Step-by-step explanation:

expand (y - 3)(y² + 3y + 9)

= y³ + 3y² + 9y - 3y² - 9y - 27

compare the coefficients of like terms with

y³ + 3y² + ay - 3y² - ay - 27

ay = 9y and - ay = - 9y ⇒ a = 9

$\bf tan^2(x)-1=0\implies tan^2(x)=1\implies tan(x)=\pm\sqrt{1} \\\\\\ tan^{-1}[tan(x)]=tan^{-1}(\pm 1)\implies x=tan^{-1}(\pm 1)\implies x= \begin{cases} \frac{\pi }{4}\\\\ \frac{3\pi }{4}\\\\ \frac{5\pi }{4}\\\\ \frac{7\pi }{4} \end{cases}$
