A rectangular parking lot is 120 feet long and 75 feet wide. Diego made another scale drawing of the parking lot at a scale of 1

andrew11 [14]

Answer:

We kindly invite you to read carefully the explanation detailed below for further details.

Step-by-step explanation:

At first we understand that Diego converted length and wide units from feet to inches ( $1\,ft = 12\,in$ ) and then he divided each term by 180, since he was using a reduction scale, so that rectangular parking lot can be represented on paper. That is:

Step 1 - Unit conversion:

$l = 120\,ft$ ( $l$ - Length)

$l = 120\,ft\times \frac{12\,in}{1\,ft}$

$l = 1440\,in$

$w = 75\,ft$ ( $w$ - Width)

$w = 75\,ft\times \frac{12\,in}{1\,ft}$

$w = 900\,in$

Step 2 - Applying scaling:

$l' = \frac{l}{180}$ ( $l'$ - Scaled length)

$l' = \frac{1440\,in}{180}$

$l' = 8\,in$

$w' = \frac{w}{180}$ ( $w'$ - Scaled width)

$w' = \frac{900\,in}{180}$

$w' = 5\,in$

A is in the shape of a quarter circle of a radius of 15cm. B is in the shape of a circle. the area of shape A is 9x the area of

RideAnS [48]

The radius of B is 2.5cm.

<h3>What is a circle?</h3>

A circle is the locus of points equidistant from a common point which is called the center of the circle.

Analysis:

Area of circle A = π $r^{2}$ /4 = π $(15)^{2}$ /4 = 225π/4

Area of circle B = π $r^{2}$

But A = 9B

225π/4 = 9 x π $r^{2}$

$r^{2}$ = 225/36 = 25/4

r = $\sqrt{\frac{25}{4} }$ = 5/2 = 2.5cm
