Answer:
Step-by-step explanation:
2x - 5y = 10
2(-3.5) - 5y = 10
-7 - 5y = 10
+7 +7
-5y = 17
-5 -5
y = -3.4
The value of y is equal to A. -3.4.
Since it is a hexagon and it has 6 sides (and we assume it is regular since it doesn't tell us otherwise) then the hexagon will have 6 lines of symmetry (:
Answer:
The circumference is similar to the perimeter in that it is the total length needed to draw the circle.
We note the circumference as c.
c = 2πr
or
c = πd
This depends on whether or not you know the radius (r) or the diameter (d)
Let’s calculate one manually, for example.
If r = 6 cm, then the circumference is c = 2π(6) = 12π cm, if writing in terms of π. If you prefer a numerical value, the answer rounded to the nearest tenth is 37.7 cm.
Suppose you only know the diameter? If the diameter is 8 cm, then the circumference is c = π(8) = 8π or 25.1 cm, rounded to the nearest tenth.
