<h3>Answer: 10.5 units</h3>

====================================================

Explanation:

Both AB and XY are the first two letters of ABC and XYZ respectively. So we have one fraction of AB/XY = 2/7.

AC and XZ are the first and last letters of ABC and XYZ respectively. We can form another fraction AC/XZ. I'm dividing in the same order of small over large to keep things consistent. As you can probably guess, the order of the letters ABC and XYZ are important so we see how the angles match up and how the proportional sides match up.

Because the triangles are similar, the two fractions formed earlier are equal to one another.

The equation we need to solve is AB/XY = AC/XZ

-----

AB/XY = AC/XZ

2/7 = 3/N ... plug in given values

2N = 7*3 .... cross multiply

2N = 21

N = 21/2 .... divide both sides by 2

N = 10.5

ZX is 10.5 units long.

The radius of a circle is 10 m. find its area to the nearest whole number.
maria [59]

\rule{200}{1}\\\dashrightarrow\large\textsf{\textbf{\underline{Given question:-}}}

<em>       The radius of a circle is 10 m. Find its area to the nearest whole number.</em>

<em />

<em />\dashrightarrow\large\textsf{\textbf{\underline{Answer and how to solve:-}}}

We're asked to find the area of the circle, which we can find using the following formula:-

\bold{Area_{(circle)}=\pi r^2}

Where:-

  • π = pi         [3.14...]
  • r=radius (10 m)

<h3>What we need to do to find the area:-</h3>

\dagger Substitute 10 for r and 3.14 for π:-

\hookrightarrow\sf{A=3.14\times(10^2)}

\bigstar On simplification,

\bold{A=3.14\times100}

\bigstar On further simplification,

\bold{A=314}

\bigstar The Area is:-

\bold{A=314\:m^2}

\square\!\!\!\!\!\!\bigstar Note:- Area is always measured in units² (units squared)

<h3>Good luck with your studies.</h3>
