Answer:
174.7 cubic meters
Step-by-step explanation:
Formula:
V = (1/3)* π * r^2 * h
V = (1/3) * π * r^2 * 17.5
From knowing the circumference: 2*(π)*r = 19.4
r = 19.4 / (2*π)
V = (1/3)* π * (19.4 /(2π) )^2 * 17.5
V = (1/3) * (19.4)^2 * (1 / (4π)) * 17.5
V = (19.4^2 * 17.5 divided by (12π)
V = 6,586.3 / (12π)
V = 6,586.3 / 37.699111842
V = 174.7070336193518 cubic meters
it is solved directly by using the formula
EF = 1.5. DF = 2.
DE is half of AB so EF is half of BC and DF is half of AC.
