Answer:
If I'm correct I think 4 is the polygon
Six point eight four.
(Note, you don't say, "Six point eighty-four" As it doesn't sound correct.
Cheers.
Area of one blade is
A=(1/2)b*h=(1/2)7*4=28/2=14
for four blades
14*4=56
1/4 of a five gallon bucket is 1 1/4 gallons.
5-1 1/4=3 3/4 gallons left to fill.
Answer: 3 3/4 gallons
We will be using the formula in looking for the volume of the cylinder which is
V = πr²h
where:
r = radius
h = height
V = volume
but in the problem V and r have values already:
r = 8
V = 4019.2
plug this in the volume equation:
V = πr²h
= 4019.2 = π* 8² * h
= 4019.2 = 64πh
= 4019.2 / 64π = h
so the answer is: h = 4019.2 /201.06193
= 19.99 is the height of the cylinder.
