The length of a rectangle is 3 centimeters less than its width. What are the dimensions of the rectangle if its area is 130 squa

a = lw

130 = l*(l+3)

130 = l^2 + 3l

l^2 + 3l - 130 = 0

(l + 13)*(l - 10) = 0

l = -13, l = 10

length can't be negative, so length is 10cm, height is 13cm

Volume Formula [Cylinder]:
$\displaystyle V = \pi r^2 h$

<em>r</em> is radius
<em>h</em> is height

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify given variables</em>.

<em>h</em> = 5 cm

<em>r</em> = 10 cm

<u>Step 2: Find Volume</u>

[Volume Formula - Cylinder] <em>Substitute</em> in variables:
$\displaystyle V = \pi (10 \ \text{cm})^2 (5 \ \text{cm})$
[Order of Operations] Evaluate:
$\displaystyle V = 500 \pi \ \text{cm}^3$
Approximate:
$\displaystyle V \approx \boxed{ 1570.8 \ \text{cm}^3 }$

∴ the volume of a cylinder whose height is 5 cm and radius is 10 cm is <em>approximately</em> 1570.8 cm³.
