Answer:
<h2>The polygon has 12 sides</h2>
Step-by-step explanation:
The sum of interior angles of a polygon is given by
<h3>( n - 2) × 180</h3>
where
n is the number of sides
From the question the sum is 1800°
Substitute the value into the above formula and solve for the number of sides
That's
( n - 2) × 180 = 1800
180n - 360 = 1800
180n = 1800 + 360
180n = 2160
Divide both sides by 180
n = 12
Therefore the polygon has 12 sides

Answer:
27.55
Step-by-step explanation:
The mean of a set of numbers is the sum divided by the number of terms.
So 49.7 + 15.8 + 22.7 + 15.1 + 32.2 + 39.1 +27.7 + 18.1 = 220.4
220.4 / 8 = 27.55
The volume is 27 cubic centimeters.
