Answer:
Sum of interior angles of polygon = (n-2)*180
1) Pentagon:
2)Hexagon:
3) Heptagon:
4) Octagon:
The circumference is 75.4 :)
Answer:
1.) can not be found
2.)V=11403.98
3.)
Step-by-step explanation:
volume = π r×r × H
r = Radius
H = height
π = 3.14
the first one does not have a radius so therefore we can NOT find the volume
the second one is π×(11×11) ×30 =11403.98
the 3rd one is π× (10×10) ×5 =1570.79
hope this helped
