V = (1/3)pi*r^2*h that's the formula to used to get the volume of the cone
The height of the given trapezoid is 7.5 m.
Step-by-step explanation:
Step 1:
The trapezoid's area is calculated by averaging the base lengths and multiplying it with the trapezoid's height.
The trapezoid's area, 
Here
is the lower base length and
is the upper base length while h is the height.
Step 2:
In the given problem,
and
. Assume the height is h m.
The trapezoid's area 


So the height of the given trapezoid is 7.5 m.
