Answer:
Yes it is parallelogram because diagonals bisect each other.
The answer is 3/4 and it was already simplified
Answer:
8/10
Step-by-step explanation:
8/10 = 80/100 > 63/100
<span>You did not include the equations that you want to assess whether they can be used to solve for the radius (r).
Likely, the equation of the circumference, C = 2*Pi*r is included, if so => r = C / (2*Pi).
If you round Pi to 3.14, the equation may be written r = C / 6.28.</span>
That would be a right-angled triangle.
