Answer:

Circ = 2 x pi x r

28.3 = 2 x 3.14 x r

r = 28.3 / (2 x 3.14) = 4.51 cm

r = 4.5 cm

Need help finding n forgot how to do this

andreyandreev [35.5K]

Answer:

$n = 3\sqrt{2}$

There are two best ways to solve this.

using cosine method:

$cos(n) = \frac{adjacent}{hypotenuse}$

$cos(60) = \frac{adjacent}{6\sqrt{2} }$

$adjacent,n = cos(60) * 6\sqrt{2}$

$n = 3\sqrt{2}$

using sine method:

$sin(n) = \frac{opposite}{hypotenuse}$

$sin(30)= \frac{n}{6\sqrt{2} }$

$n = sin(30) * 6\sqrt{2}$

$n = 3\sqrt{2}$

There are many ways, not to make it complex, these are the best ways to solve for n. Hope it helps ~

Alekssandra [29.7K]

Answer:

let dimention of original garden be x

then (x-8)(x-5) = 180

x^2 -13x -140 = 0

(x-20)(x+7)=0

x= 20 or x = -7

x = 20

original area = (20)^2

= 400 m^2
