a piece of land 120 ft by 240 ft contains a circular garden. surrounding the garden, there is a circular fence that is 20 ft in

damaskus [11]

the area of the piece of land that is not part of the garden is $28,486ft^2$ .

<u>Step-by-step explanation:</u>

Here we have , a piece of land 120 ft by 240 ft contains a circular garden. surrounding the garden, there is a circular fence that is 20 ft in diameter. We need to find what is the area of the piece of land that is not part of the garden . Let's find out:

Let's calculate area of land and circular garden , and in order to find the area of the piece of land that is not part of the garden we will subtract area of circular garden from land !

Area of Land:

Area of land is given by

⇒ $length(width)$

⇒ $120(240)$

⇒ $28,880ft^2$

Area of Garden:

Area of circular garden given by

⇒ $\pi r^2$

⇒ $\pi (\frac{D}{2})^2$

⇒ $\pi (\frac{20}{2})^2$

⇒ $\pi (10)^2$

⇒ $100\pi$

⇒ $100(3.14)$

⇒ $314ft^2$

Hence , the area of the piece of land that is not part of the garden is 28,880-314 = 28,486 . Therefore , the area of the piece of land that is not part of the garden is $28,486ft^2$ .

Hurry please answer questions 1, 2 and 3!!! thank you!!

What is the Pythagorean Theorem?

The PyTheorem states that -- actually, why not just simplify things and make it a formula?

$a^{2} + b^{2} = c^{2}$
where a and b are legs of a triangle and c is the hypotenuse of a triangle.

It is only true applying to right triangles.
Now what are the legs of a triangle?
The sides that are NOT opposite the 90 degree angle!

Now, all you have to do is find the LENGTHS of the three triangles!
Rise over run, remember?

Let's take the triangle in the top right of the coordinate plane for example.

A=(1,1)
B=(4,4)
unnamed point=(4,1)

Rise, or length of unnamed point to B?
(4,1) to (4,4)
(x,y), remember!
So? 4-1=3!

Run, or length of unnamed point to A?
(1,1) to (4,1)
Remember (x,y)?
So, 4-1=3!

The triangle has legs of 3 and 3.
Square em and add!
9+9=18
$\sqrt{18}$
$\sqrt{3*6}$
$\sqrt{ 3^{2} *2}$
$3 \sqrt{2}$

That's for length of AB!!
Now do the same for the remaining lengths!

Hope this helps!
