Answer:
Check the graph below. 
Step-by-step explanation:
A Regular Pentagon has an interior angle of 108º an an exterior angle of 72º.
Since the perimeter is 20 cm, let's draw it respecting it those properties, besides all of the three sides must have the same measure.
And since we can divide it, into three triangles, we can calculate the area using tangent.
So, let's find out the area:

Answer:
1,282.2 m³
Step-by-step explanation:
We'll use the formula 1/3*(B*h)
First, you have to find the area of the base
formula: πr²
radius: 7
7*7= 49
49*3.14=153.86
Now, multiply 153.86 by 25 (the height)
153.86*25= 3,846.5
Lastly, divide 3,846.5 by 3 and get 1,282.2 rounded
New members pay $11 each month.
Step-by-step explanation:
Given,
Total cost of new one-year membership = $160
Registration fee = $28
Let,
m be the per month fee.
Therefore,
1 year = 12 months
12m + 28 =160 Eqn 1
Subtracting 28 from both sides
Dividing both sides by 12
New members pay $11 each month.
