There can only be one reason for that . . . making
something tough out of something easy.

<u>-19 = x - 7</u>

How could you get 'x' all by itself on one side,
and everything else on the other side ?

What if you add 7 to each side ?

Then you have <em> -12 = x </em> . To your amazement, that's the solution !

-19=x-7
-19+7=x-7+7
-12=x

Given circle E with diameter CD and

irina1246 [14]

The Pythagoras is the sum of the square of two sides equal to the square of the longest side. Then the value of AC is 24 units.

<h3>What is a circle?</h3>

It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

Given circle E with diameter CD and radius EA. AB is tangent to E at A.

If AD = 10 and CD = 26.

Then the value of AC will be

We know that the tangent and radius make 90 degrees. Then the triangle is a right-angle triangle.

Then the AC is given by the Pythagoras theorem.

B² = H² - P²

B² = 26² - 10²

B² = 576

B = 24

A hemisphere has an area of 256 pi cm^2. What is its volume?

Amanda [17]

$\bf \begin{array}{llll}
\textit{surface area of a sphere}\\\\
A=4\pi r^2
\\\\\\
\textit{a hemisphere is half that}\\\\
A=\cfrac{4\pi r^2}{2}\implies A=2\pi r^2
\end{array}\qquad r=radius
\\\\\\
\textit{now, we know the area is }256\pi \implies 256\pi =2\pi r^2
\\\\\\
\cfrac{256\pi }{2\pi }=r^2\implies \sqrt{128}=r\implies \boxed{8\sqrt{2}=r}
\\\\
-----------------------------\\\\$

$\bf \textit{volume of a sphere}\\\\
V=\cfrac{4}{3}\pi r^3\qquad r=radius
\\\\\\
\textit{a hemisphere is half that}\\\\
V=\cfrac{\frac{4}{3}\pi r^3}{2}\implies V=\cfrac{\frac{4\pi r^3}{3}}{\frac{2}{1}}\implies V=\cfrac{4\pi r^3}{3}\cdot \cfrac{1}{2}
\\\\\\
V=\cfrac{2\pi r^3}{3}
\\\\\\
\textit{now, we know the radius is }8\sqrt{2}\implies V=\cfrac{2\pi (8\sqrt{2})^3}{3}
\\\\\\
V=\cfrac{2\pi (8^3\sqrt{2^3})}{3}\implies V=\cfrac{2\pi \cdot 512\cdot 2\sqrt{2}}{3}
\\\\\\
\boxed{V=\cfrac{2048\pi \sqrt{2}}{3}}$
