Answer:

Area of sector of a circle = 28.26 meter²

Step-by-step explanation:

Given:

Side of cube = 12 meter

One white section = sector of a circle

Find:

Area of one white section

Computation:

Radius of circle = Side of cube / 2

Radius of circle = 12 / 2

Radius of circle = 6 meter

One white section = sector of a circle

Area of sector of a circle = [θ/360][π][r]²

Area of sector of a circle = [90/360][22/7][6]²

Area of sector of a circle = [0.25][3.14][36]

Area of sector of a circle = 28.26 meter²

<h3>What is the matrix?</h3>

A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The $\rm a_{ij}$ element in a matrix, such as M, refers to the i-th row and j-th column element.

The matrix is given below.

$\begin{bmatrix} 1&3&8&5&\\ 5&4&6&2\\6&7&1&8\\2&9&3&7&\\\end{bmatrix}$

Then the value of a₄₁ mean the expression in 4th row and 1st column will be 2.

Then the correct option is B.

A cylinder with a radius of 1 cm and a height of 21 cm has the same volume as a cone with a height of 7 cm. What is the radius o

Natasha_Volkova [10]

Answer:

Step-by-step explanation:

The formula of a volume of a cylinder:

$V=\pi r^2H$

r - radius

H - height

We have r = 1cm and H = 21cm. Substitute:

$V=\pi(1^2)(21)=21\pi\ cm^3$

The formula of a cone:

$V=\dfrac{1}{3}\pi r^2H$

r - radius

H - height

We have V = 21π cm³ and H = 7cm. Substitute:

$\dfrac{1}{3}\pi(r^2)(7)=21\pi$ <em>divide both sides by π</em>

$\dfrac{1}{3}(7)(r^2)=21$ <em>divide both sides by 7</em>

$\dfrac{1}{3}r^2=3$ <em>multiply both sides by 3</em>

$r^2=9\to r=\sqrt9\\\\r=3\ cm$

Each year rolando saves 8% of his income. This year he saved $3000 and his salary was $2000 less than in the previous year. What

Gnoma [55]

Answer:
$39500

Explanation:
The first part of this question states that Kyle saves 8% of his salary each year. This year he earned $3000. This can be translated into
3000
=
x
⋅
8
%
, or
3000
=
0.08
x
. First you divide both sides by 0.08, which equals
3000
0.08
=
x
, which gets you $37500.
The second part of the question says Kyle earned $2000 less this year compared to last year. Simply add $2000 onto $37500 to find that Kyle earned $39500 last year.
