AC in this problem will equal 87. If the (units) is where you put the put units like feet, inches if there is units.
Answer:
A) 56.549
B) 9.425
Step-by-step explanation:
2(pi)r=56.54867
60/360x56.54867=9.425
Would it be
(2r-7)*(2r+7)
?
You know they are parallel because the lines will never intersect or meet. (Two straight lines usually mean it is parallel)

this formula is used to determine gpm (gallons per minute) of flow with a known hose diameter (d) and nozzle pressure (np). The constant (29.7) is consistent when figuring flow with in gallons with a know pressure expressed in psi (pounds per square inch).
Scenario example: a firefighter is using a handline to fight fire with an 1 3/4 inch line with a nozzle pressure of 100 psi. How much water is the firefighter flowing when fighting fire?
