A cruise ship has a large,
Arte-miy333 [17]

Answer:

28.27m^2

Step-by-step explanation:

To solve this problem, we can use the area of a circle formula as shown below:

A=\pi r^2

<em>A = area</em>

<em>r = radius</em>

<em />

First we need to find the radius.

The radius is half of the diameter. For this problem, the radius is going to be 3.

Now, plug the values into the equation:

A=\pi (3^2)

A=28.27

The window's area is 28.27m^2

4r+8+5=-15-3r ANSWER NUMBER FORM NO WORDS AT ALL
wolverine [178]

Answer:

r = -4

Step-by-step explanation:

Step 1: Write out equation

4r + 8 + 5 = -15 - 3r

Step 2: Combine like terms

4r + 13 = -15 - 3r

Step 3: Add 3r to both sides

7r + 13 = -15

Step 4: Subtract 13 on both sides

7r = -28

Step 5: Divide both sides by 7

r = -4

Need to get the values of each trig function using half angle formulas within the constraint
Marizza181 [45]
\bf cot(u)=4\qquad \pi \ \textless \ u\ \textless \ \frac{3\pi }{2}\implies cot=\cfrac{-4}{-1}\cfrac{\leftarrow adjacent}{\leftarrow opposite}&#10;\\\\\\&#10;hypotenuse\implies \sqrt{(-4)^2+(-1)^2}\implies \sqrt{17}&#10;\\\\\\&#10;cos(\theta )=\cfrac{-4}{\sqrt{17}}\implies \cfrac{-4\sqrt{17}}{17}\\\\&#10;-------------------------------\\\\&#10;

\bf sin\left( \frac{u}{2} \right)=\pm\sqrt{\cfrac{1+\frac{4\sqrt{17}}{17}}{2}}\implies \pm\sqrt{\cfrac{\frac{17+4\sqrt{17}}{17}}{2}}\implies \boxed{\pm\sqrt{\cfrac{17+4\sqrt{17}}{34}}}&#10;\\\\\\&#10;cos\left( \frac{u}{2} \right)=\pm\sqrt{\cfrac{1-\frac{4\sqrt{17}}{17}}{2}}\implies \pm\sqrt{\cfrac{\frac{17-4\sqrt{17}}{17}}{2}}\implies \boxed{\pm\sqrt{\cfrac{17-4\sqrt{17}}{34}}}

\bf tan\left( \frac{u}{2} \right)=\pm\sqrt{\cfrac{\frac{17+4\sqrt{17}}{34}}{\frac{17-4\sqrt{17}}{34}}}\implies \boxed{\pm\sqrt{\cfrac{17+4\sqrt{17}}{17-4\sqrt{17}}}}
