Answer:
(4500(Pi))/2 or 7068.585
Step-by-step explanation:
r = 15 cm
volume of a sphere:
(4/3)(Pi)r^3
Therefore:
(4/3)(Pi)15^3
15^3 = 3375
4/3 * 3375 = 4500
and since it is half a sphere (it is a bowl) the answer would be divided by two:
4500(Pi) divided by 2
14137.17 divided by 2
Answer:
The measure of the sum of interior angles of a 11-gon is
.
Each interior angle is approximately
.
Step-by-step explanation:
A convex polygon has the measure of each interior angles to be less than
.
But,
sum of interior angles of polygon = (n - 2) x 
where n is the number of sides of the polygon.
For a convex 11-gon, we have;
sum of angles of a 11-gon = (11 - 2) x 
= 9 x 
= 
Sum of angles of a 11-gon = 
To check: convex polygons' interior angles are less than
.
so that,
each interior angle of 11-gon = 
=
