Find the value of x and y
Anettt [7]

Answer:

x = 5

y = 3

Step-by-step explanation:

9x and 45 are alternate interior angles, meaning they're congruent, so set them equal to one another, like so:

9x = 45

<em><u>Divide both sides by 9:</u></em>

x = 5

<u>Solving for y</u>, the two sides are of equal length, so set them equal:

6y = 18

<em><u>Divide both sides by 6:</u></em>

y = 3

The volume of a sphere is 1928π m3 . What is the surface area of the sphere to the nearest tenth?
Rufina [12.5K]
\bf \textit{volume of a sphere}\\\\&#10;V=\cfrac{4}{3}\pi r^3\qquad \begin{cases}&#10;r=radius\\&#10;------\\&#10;V=1928\pi &#10;\end{cases}\implies 1928\pi =\cfrac{4}{3}\pi r^3&#10;\\\\\\&#10;1928\pi =\cfrac{4\pi r^3}{3}\implies \cfrac{3\cdot 1928\pi }{4\pi }&#10;=r^3\implies 1446=r^3&#10;\\\\\\&#10;\sqrt[3]{1446}=r\\\\&#10;-------------------------------\\\\&#10;\textit{surface area of a sphere}\\\\&#10;S=4\pi r^2\qquad r=\sqrt[3]{1446}\implies S=4\cdot \pi \cdot \sqrt[3]{1446^2}
