Answer:

The area of square in terms of x = 16x² -24x + 9

Step-by-step explanation:

It is stated in the question that the length of a square = 4x - 3

Formula to find the area of the square is

Area = length²

Area = ( 4x - 3 )²

by using ( a - b )² = a² + b² - 2ab

here a = 4x and b = -3

So,

(4x)² + (-3)² - 2(4x)(3)

16x² + 9 - 2(12x)

16x² + 9 - 24x

16x² -24x + 9

The area of square in terms of x = 16x² -24x + 9

(hope this helps can i plz have brainlist :D hehe)

What is the volume of a cylinder with a radius of 10 meters and a height of 4 meters?

Licemer1 [7]

Answer:

The volume of the cylinder is about 1256.6 cubic meters.

Step-by-step explanation:

The volume of a cylinder is given by the formula:

$\displaystyle V=\pi r^2h$

Where <em>r</em> is the radius and <em>h</em> is the height.

Our radius is 10 meters and our height is four meters. Substitute:

$\displaystyle V=\pi(10)^2(4)$

Evaluate:

$V=400\pi \text{ m}^3\approx 1256.6\text{ m}^3$

Thus, the volume of the cylinder is about 1256.6 cubic meters.
