Answer:
1.5
Step-by-step explanation:
6/4=1.5
9/6=1.5
This is a right triangle. To find the length of the hypotenuse a^2 + b^2 = c^2.
21^2 + 18^2 = c^2
441 + 324 = c^2
765 = c^2
27.66 km
multiply either sides by 3:
divide either sides by πr² :

Under a clockwise rotation about the origin of 90°
a point (x , y) → (y , - x)
The answer is 33.2
