Answer:64pi

Step-by-step explanation:

Circumference(c)=16pi

Circumference(c)=2 x pi x radius(r)

Substituting we get

16pi=2 x pi x r

Divide both sides by 2pi

16pi/2pi=(2xpixr)/2pi

8=r

Radius(r)=8cm

Area(a)=pi x r^2

a=pi x 8^2

a=64pi

Therefore area of the circle=64pi

<h3>What is an Equation ?</h3>

An Equation is used in determination of unknown variables in an expression .

It is given that

Brian ordered 3 large cheese pizzas and a salad.

The salad cost $4.95

Total amount spend = $47.60

Tip = $5

The amount spend in food is $ 47.60-5

= $42.60

Let the price of Pizza is x then the equation that can be formed to determine the price of pizza is

3x + salad = 42.60

3x + 4.95 = 42.60

3x = 37.65

x = $12.65

Therefore each pizza cost $ 12.65

Find sin X, cos X, and tan X as<br> a fraction in simplest form.

cupoosta [38]

Answer:

sin X = $\frac{4}{5}$

cos X = $\frac{3}{5}$

tan X = $1\frac{1}{3}$

Step-by-step explanation:

First, find what the hypothenuse is:

$c^{2} = a^{2} + b^{2}$

$c^{2} = 18^{2} + 24^{2}$

$c^{2} = 324 + 576$

$\sqrt{c^{2}} = \sqrt{900}$

c = 30

$sine = \frac{opposite}{hypothenuse}\\\\$

sin x = $\frac{24}{30} = \frac{4}{5}$

$cosine = \frac{adjacent}{hypothenuse}$

cos x = $\frac{18}{30} = \frac{3}{5}$

$tan = \frac{opposite}{adjacent}$

tan x = $\frac{24}{18} = 1\frac{6}{18} = 1\frac{1}{3}$
