Cone 1:Formula=pir^2h/3
=Approximately 452.39
Cone2:Approximately,904.78
Cone 3:Approximately,733.04

Answer:
C-(7)
Step-by-step explanation:
Given figure is a trapezoid and 21 - x is the mid segment.
Therefore by mid-segment formula of a trapezoid, we have:
21 - x = 1/2(17 + 11)
21 - x = 1/2 * 28
21 - x = 14
21 - 14 = x
7 = x
x = 7
