So remember that the area of a circle is A = π * r^2, with r = radius. In this case, the radius is 1.5, and with that info our equation is A = π * 1.5^2 .
For this, all you need to do is solve the exponents, and your answer is A = 2.25π yds^2

1. False
2. False
3. True
Step-by-step explanation:
1. The diagonals of a rectangle always form four congruent triangles, which is a false statement.
The counter-statement will be, the diagonals of a square always form four congruent triangles.
2. A quadrilateral has perpendicular diagonals. Is this enough to determine what type of quadrilateral it is?
The answer is no.
The counter-statement will be, a quadrilateral has perpendicular diagonals, then it may be a rhombus or a square.
3. Explain why drawing a diagonal on any parallelogram will always result in two congruent triangles and it is true that the two triangles will be congruent as the opposite sides of the parallelogram are equal and there is a common side which is the diagonal itself.
Therefore, using SSS criteria the triangles are congruent. (Answer)
3000×5=15000.so 6÷15000=2500
so the wind speed us 2500 km per hour
