Find the surface area of a hemisphere that has a volume of 486π <img src="https://tex.z-dn.net/?f=cm%5E%7B3%7D" id="TexFormula1"
Xelga [282]

\textit{volume of a hemisphere}\\ V=\cfrac{4\pi r^3}{3}\cdot \cfrac{1}{2}~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ V=486\pi \end{cases}\implies 486\pi =\cfrac{4\pi r^3}{6} \implies 6(486\pi )=4\pi r^3 \\\\\\ \cfrac{6(486\pi )}{4\pi }=r^3\implies 729=r^3\implies \sqrt[3]{729}=r\implies \boxed{9=r} \\\\[-0.35em] ~\dotfill

\textit{surface area of a hemisphere}\\\\ SA=4\pi r^2\cdot \cfrac{1}{2}\implies \stackrel{\textit{we know that r = 9}}{SA=2\pi (9)^2}\implies SA=162\pi \implies SA\approx 508.94

Which equation is true when p=0.6
e-lub [12.9K]

Answer:

B

Step-by-step explanation:

Its not A because when you plug in 0.6 in for P it gives you 6.6=1.8. (0.6)+6=1.8

Its B because when you plug in 0.6 in for P it gives you 6=6.

10(0.6)=6

Its not C because when you plug in 0.6 in for P it gives you 0.36=10.

0.6(0.6)=10

Its not D because when you plug in 0.6 in for P it gives you -0.4=0.4.

(0.6)-1=0.4
