Since 0, -180 is the rotation and if you look at the other rotations like 90, 180 the first rotation would be different. so 0, 180 is the same as 0, -180 because they both would be a full rotation of a 180 rotation. The first number "0 ," would have to be the same.
To find the area of a quarter circle, you simply take a quarter of a full circle. As all quarters are equal, this means that the formula would be <span><span>π<span><span>r2</span>4</span></span><span>π<span><span>r2</span>4</span></span></span><span>. But wait, there's more. If you notice, </span><span><span>π<span><span>r2</span>4</span>=π<span><span>r2</span>2</span></span><span>π<span><span>r2</span>4</span>=π<span><span>r2</span>2</span></span></span><span>. This coincides with the circle formula, just with half the radius. Notice anything? A quarter of a circle can be calculated in the same way a circle a quarter the size can. This means that a quarter circle is equal to a circle a quarter size. In this same way, a ninth of a circle is equal to a circle of one ninth the size.</span>
Let's first figure out how much it flies in a hour,
560/5 = 112
8 x 112 = 896
(112 mph)
Always will be your answer ;D
1.x=-6
2. y=-8/3 + 2x/3
3. x+3y+3x
