Answer:

Circumference: 6πcm

Area: 81π mm^2

Step-by-step explanation:

1. C = πd

C = 3.14159 * 6

C = 18.84cm OR C = 6πcm

2. A=πr^2

A = 3.14159 * (9^2)

A = 254.46mm OR 81π mm^2

Answer:

5) c. 6 pi cm

6) A. 81 pi mm^2

Step-by-step explanation:

5) Circumference of a circle = pi d

d = 6 cm

C = 6 pi cm

Answer

c. 6 pi cm

A = pi r^2

r = d/2 = 18/2 = 9

A = pi 9^2

A = 81 pi mm^2

Answer

A. 81 pi mm^2

Jessie is fencing in a rectangular plot outside of her back door so that she can let her dogs out to play. She has 60 feet of fe

DerKrebs [107]

Answer:

Dimensions are length 15 feet and width 30 feet.

Maximum area of the plot is 450 feet².

Step-by-step explanation:

Let the length of the plot = x feet and width = y feet.

Since, the amount of fencing to be applied on the three sides of the plot is 60 feet.

We have,

$2x + y = 60$ i.e. $y=60-2x$

Now, Area of the rectangular plot = Length × Width

i.e. Area of the rectangular plot = $x \times y$

i.e. Area of the rectangular plot = $x\times (60-2x)$

i.e. Area of the rectangular plot = $-2x^2+60x$

<em>Since, the maximum of the quadratic equation $ax^2+bx+c$ will be obtained at $x= \frac{-b}{2a}$ .</em>

Then, the maximum of the area of the plot is at the point $x= \frac{-60}{2\times (-2)}$ i.e. x= 15

Then, maximum area of the rectangular plot = $-2x^2+60x$

i.e. maximum area of the rectangular plot = $-2\times 15^2+60\times 15$

i.e. maximum area of the rectangular plot = -450+900 = 450 feet²

Hence, Maximum area of the plot is 450 feet².

Then, $y=60-2\times 15$ implies $y=60-30$ i.e. y= 30.

Hence, the maximum area is enclosed by the length 15 feet and width 30 feet.
