Answer:
D) 1260°
Step-by-step explanation:
In an n-sided polygon, the sum of all angles is equal to (n-2)*180°.
Look at it this way - let's add a point in the middle and connect it to each vertex. Then we've got n triangles for a total of n*180°, but all of the angles at the middle point aren't "part" of the polygon, so a full 360° angle should be subtracted, giving us n*180°-360° = (n-2)*180°
You can easily confirm that it works for triangles and quadrangles ;)
The figure in the picture has 9 sides, so the sum of angles is (9-2)*180° = 7*180° = 1260°
Answer:
The approximate volume of the cone is 14 cube inches.
Step-by-step explanation:
Circumference of the base of the cylinder = 3π inches
Height of the cylindrical piece of wood = 6 inches
volume of a cone = 
h
But,
circumference = 2πr
3π = 2πr
r = 
= 1.5 inches
Radius of the base of the cylinder is 1.5 inches.
So that;
volume of cone = x 
x 
x 6
= x x 
x 6
= 14.143
volume of cone = 14.143 cube inches
The approximate volume of the cone is 14 cube inches.
25 is the answer, 25 is the lowest number they both go into

Answer:
29.50
Step-by-step explanation:
18% = 0.18
if you do 25x0.18 then you get 4.50
then add 4.50 to 25 to get 29.50
