Two rectangular lawns are similar shapes.

Reil [10]

Answer:

The answer to your question is Area = 37500 ft²

Step-by-step explanation:

Data

lawn 1 lawn 2

width = 550 ft width = 250 ft

Area = 181500 ft² Area = ?

Process

1.- Find the length of lawn 1

Area = length x width

-solve for length

length = Area/width

-Substitution

length = 181 500 ft²/ 550

-result

length = 330 ft

2.- Find the length of lawn 1 using ratios and proportions

550 : 330 :: 250 : x

x = (250 x 330) / 550

x = 150 ft

3.- Find the area of lawn 2

-Substitution

Area = 250 x 150

-Result

Area = 37500 ft²

A semi-circle with a diameter of 4 is rotated around its diameter one full rotation, what is the volume of the solid generated b

iris [78.8K]

The volume of the solid generated by the revolution is 33.5 cubic units.

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

It is given that, the diameter of the semi-circle is 4 and it is rotated to one full rotation around its diameter.

A solid generated when a semicircle is being rotated about its diameter is called a "SPHERE".

Therefore, the volume of the solid generated by the revolution is the volume of the sphere.

The formula for volume of the sphere is given by,

Volume of sphere = (4/3)πr³

where, r is the radius and π has the default value of 3.14

Here, the given diameter is 4.

To find the radius = diameter/2

radius = 4/2 = 2.

Now, to calculate volume of sphere substitute r=2 and π=3.14

volume of the sphere = (4/3)×3.14×2³

⇒ (4/3)×3.14×8

⇒ 100.48 / 3

⇒ 33.49 (approximately 33.5)

Therefore, the volume of the solid generated by the revolution is 33.5 cubic units.

Solve the quadratic equation: 3x2 + x - 5 = 0

Yuri [45]

Hey there!

$3x^2 + x -5 = 0$

This equation is in standard form, which is $ax^2+bx+c=0$ .

We are going to solve this with the quadratic equation, so we need to find the values for a, b, and c in the given equation. We can just look at it and identify the variables.

a = 3, b = 1, c = -5

Let's plug these values into the quadratic equation:

$x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$
