Answer:
72°
Step-by-step explanation:
In a properly constructed pie chart, the proportion of the circle devoted to each section is the same as the proportion of that section to the the whole.
(6 swim days)/(30 days) = (swim pie angle)/(360°)
Multiply by 360° to find ...
swim pie angle = (360°)(6/30) = 72°
72° of the circle should represent swimming.
Answer:
A. ![(x-4)^2+(y-3)^2=25](https://tex.z-dn.net/?f=%28x-4%29%5E2%2B%28y-3%29%5E2%3D25)
Step-by-step explanation:
Radius:
The length of diameter
is the distance between A and B.
![d=\sqrt{(8-0)^2+(6-0)^2}=\sqrt{64+36}=\sqrt{100}=10\\\\radius(r)=\frac{d}{2}=\frac{10}{2}=5](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%288-0%29%5E2%2B%286-0%29%5E2%7D%3D%5Csqrt%7B64%2B36%7D%3D%5Csqrt%7B100%7D%3D10%5C%5C%5C%5Cradius%28r%29%3D%5Cfrac%7Bd%7D%7B2%7D%3D%5Cfrac%7B10%7D%7B2%7D%3D5)
Centre:
Since A and B are end points of the diameter, centre is the mid point of these two. Let
be the centre of the circle.
![x=\frac{8+0}{2}=4\\\\y=\frac{6+0}{2}=3\\\\](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B8%2B0%7D%7B2%7D%3D4%5C%5C%5C%5Cy%3D%5Cfrac%7B6%2B0%7D%7B2%7D%3D3%5C%5C%5C%5C)
Centre is ![(4,3)](https://tex.z-dn.net/?f=%284%2C3%29)
Equation of circle:
If
is the centre of the circle and
be the radius. Equation of circle is given by:
![(x-a)^2+(y-b)^2=r^2](https://tex.z-dn.net/?f=%28x-a%29%5E2%2B%28y-b%29%5E2%3Dr%5E2)

Input data
In any right triangle, the sine of an angle x is the length of the opposite side (O) divided by the length of the hypotenuse (H). In a formula, it is written as 'sin' without the 'e':
