#20 is this the correct answer bc I'm not sure what it means when it says "what are the areas of the two sectors" does that mean
Lelechka [254]
\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta\pi r^2}{360}\qquad 
\begin{cases}
r=4\\
\theta=112
\end{cases}\implies A=\cfrac{112\cdot 16\cdot \pi }{360}\implies \boxed{A=\cfrac{224}{45}\pi}
\\\\\\
A\approx 15.64\\\\
-----------------------------\\\\
\textit{area of a circle is }\pi r^2\textit{ so the other side will be}
\\\\\\
\pi r^2-\cfrac{224\pi }{45}\implies 16\pi -\cfrac{224\pi }{45}\implies \boxed{\cfrac{496\pi }{45}}\implies A\approx 34.68

In which number is the value represented by the digit 9 equal to 1/10 of the value represented by the digit 9 in the number 73,9
marshall27 [118]

Answer: 90

Step-by-step explanation:

In the number 73,951, the digit 9 is on the third position, so you need to put the number of the position minus one zeros before it: ( position number 3, 3 - 1 = 2, so we put 2 zeros)

the 9 in that digit represents a 900.

now, 1/10 times that number is:

900*(1/10) = 900/10 = 90

then the answer is 90.

In the number 90, the value represented by the 9 is equal to 1./10 times the value represented by the 9 in 73,951
