Answer:
Step-by-step explanation:
we know that
The volume of a cylinder (water pipe) is equal to

In this problem we have
-----> the radius is half the diameter
----> convert to inches

42600-25800=16800
16800/15=1120
42600*x=100*1120
x=112000/42600=2.62%
Answer:
98 degrees
Step-by-step explanation:
m<H = 45, m<F = 53
180 = 45 + 53 + (180-x)
82 = 180-x
x+82 = 180
x = 98
