Answer:
44x/7
Step-by-step explanation:
Radius=r=xcm
Circumference=2πr
➜2πx
➜2×22/7×x
➜44/7×x
➜44x/7
First we can either add 19 and 11, or we can do this another way.
19 + 11 = 30 To find how much thirty tens are, just add a 0 on the end of 30: 300
The other longer way to do it is: add a 0 to 19: 190, then add a 0 to 11: 110
110 + 190 = 300
There is your answer!

Answer:
x = 55
Step-by-step explanation:
given x varies inversely as x then the equation relating them is
x = 
← k is the constant of variation
to find k use the given condition x = 11 when y = 3
k = xy = 11 × 15 = 165
x = 
← variation equation
when y = 3, then
x = 
= 55
