Answer:
The height of the water is 
Step-by-step explanation:
step 1
Find the volume of the tank
The volume of the inverted right circular cone is equal to

we have


substitute


step 2
Find the 25% of the tank’s capacity

step 3
Find the height, of the water in the tank
Let
h ----> the height of the water
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional

substitute

where
r is the radius of the smaller cone of the figure
h is the height of the smaller cone of the figure
R is the radius of the circular base of tank
H is the height of the tank
we have
-----> volume of the smaller cone
substitute

Simplify


Answer:
The area of the face is 15 cm^2
Step-by-step explanation:
The formula for volume is
V = Bh where B is the area of the base and h is the height
90 = B * 6
Divide each side by 6
90/6 = 6B/6
15 = B
The area of the face is 15 cm^2
