Answer:
201 ft³ (201 cubic feet)
Step-by-step explanation:
The volume of a cylinder is given as:
V = pi * r² * h
Where r = radius of the cylinder
h = length of the cylinder.
The diameter of the cylindrical pipe, d = 4 ft
The radius of the cylindrical pipe, r = d/2 = 4 / 2 = 2 ft
The length of the cylindrical pipe, h = 16 ft
The volume of the cylindrical pipe is:
V = 3.14 * 2² * 16
V = 200.96 ft³ = 201 ft³ (to the nearest whole number)
The volume of the cylindrical pipe is 201 ft³ (201 cubic feet)
Answer:
Step-by-step explanation:
look this solution
7/9 would be irrational, I think.
Answer:
Step-by-step explanation:
it can be simplified to 
. if you multiply each side by the denominator, it becomes 
since 
and cotan is the reciprocal of that. Because 
so multiplying each side gives 
, and 
is equal to 1.
