Step-by-step explanation:
Diameter = 14
Radius = 7 inches
Volume = (4/3)×3.14×7³ = 1436.026667 inches³

The first one is 0 and the second one is the same
Answer:
36.
Step-by-step explanation:
sec^2 (π/9) = 1 / cos^2 (π/9) = 1.13247
sec^2 (2π/9) = 1 / cos^2 (2π/9) = 1.70409
sec^2 (4π/9) = 1 / cos^2 (4π/9) = 33.1634
Adding these gives us 36 to the nearest whole number
