Well, if the diameter is 4 u, the radius is 2 u.
The formula for finding the circumference of a circle is 2*pi*r
In this case, we'd just plug in 2 for r.
2*pi*2
4pi

Answer:
f = -
Step-by-step explanation:
Given f varies directly with m then the equation relating them is
f = km ← k is the constant of variation
To find k use the condition f = - 19 when m = 14, thus
- 19 = 14k ( divide both sides by 14 )
- = k
f = - m ← equation of variation
When m = 2, then
f = - × 2 = -

Step-by-step explanation:
Answer:
No because if you cross multiply 50x3= 150 while 27x6 is like 162 so no
