6.7 is closer to 7 so you would round it to 7
Answer:
5.85 Miles
Step-by-step explanation:

Just create a problem and figure it out.
Let's say the original diameter is 4. This means the radius is 4/2 = 2.
A = 2πr^2
A = 2π(2)^2
A = 2π(4)
A = 8π
The new diameter is 50% larger than the original.
50% of 4 is 2. 2 + 4 = 6. So the new diameter is 6. The radius is 6/2 = 3.
A = 2πr^2
A = 2π(3)^2
A = 2π(9)
A = 18π
Old area was 8π, new area is 18π. Now divide the difference from the original area:
18π - 8π = 10π
10π/8π = 1.25 * 100 = 125%
The series is an geometric series, terms are generated by multiplying x.
<span>A regular polygon is, by definition, a polygon with congruent interior angles and sides. Thus, if we rotate n-gon about its centre, we will repeat the polygon n times before it comes back to its original position.
a. The interior angles are congruent to their exterior angles.
This means that all angles are 90 degrees, so
true for a square or rectangle,but FALSE for a 25-gon.
b.All the diagonals are congruent.
It is true for all regular polygons, but not sufficient to make the polygon regular.
Counter example: A rectangle has all diagonals congruent, but it's not a regular quad. So FALSE.
c.Opposite pairs of sides are parallel.
All even-number sided regular polygons will satisfy this property, but not sufficient to make a polygon regular. Counter example: A rectangle with different adjacent sides. So FALSE.
In the case of a 25-gon, there are no "opposite" sides.
d. All interior angles and all sides are congruent.
This will undoubtedly create a regular polygon, since it satisfies the definition of a regular polygon. If we rotate it about its centre, we can repeat the same 25-gon 25 times. So TRUE</span>
