So.. hmm notice the picture below... if the diameter is 20, the radius is half that

thus $\bf \textit{area of a circle's sector}\\\\
A=\cfrac{\theta\pi r^2}{360}\qquad 
\begin{cases}
r=radius\\
\theta=\textit{angle in degrees}
\end{cases}$

Rise over run

Line 1:

$\frac{(7)-(3)}{(6)-(-6)}$

$\frac{4}{12}$

Simplify:

1/3

Line 2:

$\frac{(2)-(1)}{(-3)-(-6)}$

$\frac{1}{3}$

1/3

1 is Paralell to 2 because they have the same slope

I hope this helps! :D

The perimeter of a rectangle is 72 in. The base is 3 times the height. Find the area of the rectangle

Dovator [93]

Answer:

243 in²

Step-by-step explanation:

Step 1. Calculate the base and height of the rectangle

We have two conditions:

(1) 2b+ 2h = 72 in

(2) b = 3h Substitute in (1)

2(3h) + 2h = 72 Remove parentheses

6h + 2h = 72 Combine like terms

8h = 72 Divide by 6

h = 9 in Substitute in(2)

b = 3 × 9

b = 27 in

Step 2. Calculate the area of the rectangle

A = bh

A = 27 × 9

A = 243 in²

The area of the rectangle is 243 in².
