The answer is D. 0.5095

You have to use your calculator to solve this problem, but it is very simple. As long as you press all the right buttons, the calculator does all the work for you!

It may vary based on your calculator type, but basically you have to press the tan (or tangent) button and then press the numbers 27. Then hit enter. The number that comes up should say: 0.5095254495, which you then round to 0.5095.

Make sure when you do this problem that your calculator is in degree mode and not radian. If it's in radian mode it will give you the wrong answer.

Hope this helps!

A sphere has a volume of Vequals=3600 in cubedin3. Find its surface area.
Mice21 [21]
\bf \textit{volume of a sphere}\\\\
V=\cfrac{4}{3}\pi r^3\qquad 
\begin{cases}
r=radius\\
------\\
V=3600
\end{cases}\implies 3600=\cfrac{4}{3}\pi r^3
\\\\\\
3600=\cfrac{4\pi r^3}{3}\implies \sqrt[3]{\cfrac{3\cdot 3600}{4\pi }}=\boxed{r}\\\\
-----------------------------\\\\
\textit{surface area of a sphere}\\\\
S=4\pi r^2\implies S=4\pi \left(\boxed{\sqrt[3]{\cfrac{3\cdot 3600}{4\pi }}}  \right)^2
