$(x - 3)(x - 3)(x - 3)(x - 3)(x - 3)$
$(x^{2} - 6x + 9)(x^{2} - 6x + 9)(x^{2} - 6x + 9)(x - 3) \\(x^{4} - 12x^{3} + 54x^{2} - 108x + 81)(x - 3) \\x^{5} - 15x^{4} + 90x^{3} - 270x^{2} + 189x - 324$

A) $\frac{2 \frac{1}{4}}{ \frac{1}{2}}$
b) $\frac{1}{2}$ • 2 = 1
so $\frac{9}{4}$ • 2 = $\frac{9}{2}$ cups (which is $4 \frac{1}{2}$ )

If a wheel has a diameter of 15 centimeters what is the area of the wheel nearest centimeter

maw [93]

Answer:

Step-by-step explanation:

A diameter is two times longer than a radius. Therefore, if the diameter

d = 15cm, then the radius r = (15cm) : 2 = 7.5cm.

The formula of an area of a circle:

$A=\pi r^2$

Substitute:

$A=\pi(7.5)^2=56.25\pi\ cm^2$

$\pi\approx3.14$

Then

$A\approx(56.25)(3.14)\approx177\ cm^2$
