I’m learning this too.. so what you do it see what will the number he if it was a while line so to find that out you will add 7+7 and get 14 so that’s the whole
So 7 x 7 will equal 49 and 49 x 3.14 will give you 153.86 as the answer

Formula
------------------------------------------------------
Circumference = πD
------------------------------------------------------
Find Diameter
------------------------------------------------------
3600π = πD
D = 3600 ← Divide by π on both sides
------------------------------------------------------
Answer: Diameter = 3600 unit

Answer:
21.6 $ / h
Step-by-step explanation:
Since it is a raise you'll calculate by multiplying the $ / h by (1 + % / 100)
In this case 1 + % / 100 = 1 + 20 / 100 = 1 + 0.20 = 1.20
1.20 * 18 = 21.6 $ / h
NB.:
If it was a decrease by 20 % => 1 - 20 / 100 = 1 - 0.20 = 0.80
You would multiply the $ by 0.80.
