Step-by-step explanation:
3.7x - 0.20x = 17.5
3.5x = 17.5
x = 17.5/3.5
x = 5
All you have to do is find the square root of 441
the square root of 441 is 21
the formula for Area is LxW so 21x21=441
The length of one side 21 square feet

Step-by-step explanation:
Answer:
height = 12 feet
Step-by-step explanation:
r (radius of circle) = 7 ft
pi = 3.14 (in this context)
v = 1/3 * (or pi * radius squared) * h
r squared = 49 ft
v = 1/3 3.14 * 49 * h
v = 1/3 153.86 * h
3v = 153.86 * h
v = 196π
v = 615.44
3v = 1,846.32
1,846.32 = 153.86 * h
h = 12 ft.
