Step-by-step explanation:
we know that
The volume of the trapezoid pyramid is equal to

where
B is the area of the trapezoid base
h is the height of the pyramid
we have


substitute and solve for h


The formula to find the Length of the arc = (2r) (θ / 360°)
Substituting the values
Length of the arc = (2) (40) (324° / 360°)
By further calculation
= (80) (0.9)
So we get
= (80) (3.14) (0.9)
= 226.08 cm.
Therefore, the length of the arc is 226.08 cm.
