A=4pi r^{2} solve for r

Mathematics
1 answer:
lara [203]2 years ago
5 0
             A = 4πr²          Divide both sides by 4π
     A / 4π = r²               Find the square root of both sides
√(A / 4π) = √(r²)          Cancel out the square with the square root
√(A / 4π) = r                Switch the sides to make it easier to read
              r = √(A / 4π)

What is -1.1 repeating as a fraction
Thepotemich [5.8K]

Hey \\ There!

\frac{-1.1}{1} ( \frac{10}{10} )\\ \\ -1.1(10) = -11   \\ \\ 1(10)= 10 \\ \\ \\  Fraction:  \frac{-11}{10} this is also equal to: -1\frac{1}{10}

Your answer would probably be: \frac{-11}{10} =  -1\frac{1}{10}

Good luck on your assignment and enjoy your day!

-8q+6+5q-3 what does q equal
alisha [4.7K]
In this equation q is equal to 1
STEPS:
-8q+6+3q-3 (original equation)
-3q+3 (combine like terms)
3q=3 (move -3q to the other side so you can divide to get what q is. When you move it over to the other side it becomes positive)
q=1 (divided)

Let sin A = 12/13 with 90º≤A≤180º and tan B = -4/3 with 270º≤B≤360º. Find tan (A - B).
Juliette [100K]
\tan(A-B)=\dfrac{\tan A-\tan B}{1+\tan A\tan B}=\dfrac{\tan A+\frac43}{1-\frac43\tan A}

\cos^2A=1-\sin^2A\implies\cos A=\pm\sqrt{1-\sin^2A}

where the sign of the root is chosen depending on the value of A. Since we know 90^\circ, it follows that -1, i.e. \cos A, which means

\cos A=-\sqrt{1-\sin^2A}=-\dfrac5{13}

\implies\tan A=\dfrac{\sin A}{\cos A}=\dfrac{\frac{12}{13}}{-\frac5{13}}=-\dfrac{12}5

\implies\tan(A-B)=\dfrac{-\frac{12}5+\frac43}{1+\frac43\times\frac{12}5}=-\dfrac{16}{63}
