Area of a regular polygon = 1/2 x apothem x perimeter
We know that each side is 10, because if you draw a segment from the center to a vertex it creates a 30-60-90 triangle (those are the angles). This type of triangle has a ratio for its sides where the longer side is radical three times as long as the shorter leg. This shorter leg happens to be half of a side of the polygon. Knowing that the polygon has 6 sides, we can multiply 10 by 6 to get the perimeter.
Area of polygon = 1/2 x apothem x perimeter = 1/2 x 5

x 60
=30 x 5

= 30 x 5 x <span>1.73205080757
= 150 x </span><span>1.73205080757
= </span><span>259.807621135
To the nearest tenth of a cm, the area of the polygon is 260 cm squared</span>
Step-by-step explanation:

In order for us to find the circumference, we need to find the radius from the given area by rearranging the area formula.




Now that we have the radius, we can find the circumference.



So, when given 113.1 in sq for the area, the circumference of the circle is 37.68 in.
Answer: 11
Step-by-step explanation:
-4×4= - 16
-16+5= 11
Answer:
The value is 5 1/2 ⇒ second answer
Step-by-step explanation:
* At first we must simplify each radical and then add the terms
- To simplify the cube root lets change the number under it
to a number with power of 3 and then change radical to
a rational exponent
∵ ∛x = x^1/3
∵ 343 = 7 × 7 × 7 = 7³
∴∛343 = 
* WE will use the rule ⇒ 
∴ 
* We will do the same with ∛(-8)
∵ -8 = -2 × -2 × -2 = (-2)³
∴∛(-8) = 
* Lets solve the problem
# ∛343 + 3/4 (∛-8) = 7 + (3/4) × (-2) =
7 + (-3/2) = 11/2 = 5 1/2
* The value is 5 1/2
A We can observe independently vertical component of arrows speed. Since there isn't vertical speed at start we can observe this case as free fall where formula for traveled distance is:
h = 1/2*g*t^2
we can express t
t = √2h/g
t = 1,427s
after 1.427 seconds in air arrow will hit ground.
B. The range we get simply by calculating how much distance will arrow travel in 1.427 seconds at speed of 64.5m/s. speed is not changing because we are ignoring air resistance.
s = t*v = 93.468m
