Answer:
Diameter is equal to 38 cm.
Step-by-step explanation:
We know that the circumference equals πd (where d is the diameter).
If we round the value of π to 3.14 then we will get...
πd = 119.32
(3.14)d = 119.32
d = 119.32 / 3.14
d = 38 cm
Therefore the diameter is equal to 38 cm

Answer:
39.30
Step-by-step explanation:
When you divide you usually don't get a full number, so, when you get a answer that has a long decimal number, you round the two numbers after the decimal point, so, 39.29 would be 39.30. I'm pretty sure that is your answer. If it is wrong I sincerely apologize.
From the Pascal's triangle, take the correct level. Use it to write the binomial expansion. Or use nCr.
(x+y)^n
Remember that the powers of x start at n, and that the sum of the x and y powers is always n.
