For #4, we know V = lwh
We have the values
5184 = 2(18)h
Solve for h
5184 = 36h
144 = h.
for # 3:
we know A = pi r^2
We have
A = 3.14 * 6^2
A = 3.14 * 36
A = 113.04
for #2:
We know C = 2pi *r
C = 2(3.14)(14)
C = 28(3.14)
C = 87.92
for #1:
C = 2pi * r
C = 2(3.14)(26.3/2)
C = 2(3.14)(13.15)
C = 26.3(3.14)
C = 82.582

Inscribed is a polygon inside a circle with all points on a given point in the circle. Circumscribed is a circle inside a polygon with any given point touching just one point on the polygon. Hope this helped.
Answer:
Step-by-step explanation:
arc BE is the same as the interior angle, or 76°
BE = 76 °
we can also find arc CE the same way, b/c we can see that the interior angle is the suppment with 76 or 180-76 = CE or 104°
Now we know all the arcs but arc CD
so use the idea that all the way around the circle is 360°
360 = 76 + 104 + 140 + CD
360 - 76 - 104 - 140 = CD
40 = CD
CD = 40 °
