Answer:
Step-by-step explanation:
Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation.
Answer:
parallelogram, quadrilateral
Step-by-step explanation:
a rectangle is a quadrilateral because it has 4 sides.
it is a a parallelogram because it has two sets of parallel lines in those four sides.
in order for a quadrilateral to be a rhombus, all sides must be the same length. (if a rectangle is a rhombus, it is a square.)

Both equations are equivalent, so there are infinitely many solutions.
It would be OD because it is going down by 8 each time and you can see that D goes down by 8 each time
180 - x = r is true.
Thats the only one which is true.
