Answer:
Diameter of the pipe ≈ 6.77 ft
Step-by-step explanation:
Volume of a cylinder = πr²h
Here, r = Radius of the cylindrical pipe
h = Length of the pipe
Volume of the pipe = 900 ft³
Length of the pipe = 25 ft
By substituting the given values in the formula,
900 = π(r)²(25)
r² = 
r = √11.459
r = 3.385
Diameter = 2(radius)
= 2(3.385)
= 6.77 ft
This is the concept of algebra, we are required to add up the terms given above, here we shall have:
3/(4x)+21/(8x)+26x+15
when we sum up we get:
27/(8x)+26x+15
=(27+208x^2+120x)/(8x)
The simplified form of the summation of the terms is:
(27+208x^2+120x)/(8x)
Parentheses then exponents then multiply then divided then add then substract
8 7/8+(7 5/6) - 2 1/3)
71/8 +(47/6 - 7/3)
71/8+ 11/2
115/8
