Step-by-step explanation:
A
The volume (V) of a cylinder is calculated using the formula
V = πr²h ( r is the radius of the base and h is the height )
here d = 3 ⇒ r = 1.5 and h = 8, thus
V = π × 1.5² × 8
= π × 2.25 × 8 = 18π ft³
--------------------------------------------------
B
We require to calculate the radius to obtain the diameter, hence
πr² × 2 = 18π ← volume of tank B = volume of tank A
2πr² = 18π ( divide both sides by 2π )
r² = 9 ( take the square root of both sides )
r = = 3
Hence diameter = 2 × 3 = 6 ft

Answer:
ok so we know that a triangle is 180 degrees.
so i can take the info and figure out the f,g,d,i all equal 90 degrees so i can figure out that 90+51=141
180-141=39
so angle a is 39
the two bigger triangles are equal and the two smaller ones are equal...
so we know that
a=39
b=62
c=51
d=90
e=39
f=90
g=90
h=28
i=90
