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
