Hello from MrBillDoesMath!
Answer:
3.14
Discussion:
C = circumference, r = radius, d = diameter = 2 r
For a circle, C = 2 Pi r = d Pi
Substituting the values in the question gives
C = d Pi
28.26 = 9 Pi => divide both sides by 9
Pi = 28.26/9 = 3.14
Thank you,
MrB
Answer:
4
Step-by-step explanation:
x equals 4 when y equals 9 on that line
It is 12 liters. 2.75 gallons is approximately 10.41 liters and 12 liters is more than 10.41 liters.
Answer:
No
Step-by-step explanation:
If you mean they are the sides lengths,
33^2+ 56^2 != 66^2
3136 != 4356
Answer:
H = 20.5 hours
I = 19.5 Hours
Step-by-step explanation:
Start by creating a system.
I = time which the inlet pipe takes alone to fill the pond
H = time which the hose takes alone to fill the pond
10/I + 10/H = 10
H - I = 1
H = 20.5 hours
I = 19.5 Hours
