Area is pi x radius^2
if we divide by pi, we get 16.55211408.
If we square that number, we get 4.068428945. This number is the radius.
Circumference is diameter x pi or 2 x raidius x pi
So multiply that number by 2 and pi and we get 25.56269297 as the circumference.
First, you need to remember how to obtain the answer.
1) (velocity)*(cosine of the angle)2)(velocity)*(sine of the angle)
Since the plane is traveling 45 degrees below the horizon the angle that we will be using is 180+45=225.
Therefore we will have,
150* cos(225) = -81.31
150*sin(225) = -81.31
*In the unit circle, the coordinates of 225 are -squareroot(2) divided by 2 for both sin and cos, which explains why we have the same answer for both sin and cos.
The answer being negative makes sense since the speed is decreasing due to the fact that the plane is traveling below horizontal.
Answer:
Step-by-step explanation:
9 - ratio 3:5
10 1/8 + 1/4 = 1/8 + 2/8 = 3/8 of the pizza eaten
so 5/8th of the pizza is left
