Since you are solving for diameter, and the equation is given to you, just isolate the variable for diameter (d).
(C)/π = (πd)/π
d = C/π is your formula you will use.
Plug in 56 for C
d = 56/π
d = ~17.825

Step-by-step explanation:
Answer:
The value of Cos (-Ф)
.
Step-by-step explanation:
Given Trigonometric function as :
sin( - Ф ) = 
- sin Ф = 
So, sin Ф = 
Now, as sin Ф = 
So ,
= 
So, perpendicular = 3
And hypotenuse = 5
Now,<u> From Pythagoras Theorem</u>
Base ² = Hypotenuse² - Perpendicular²
Or, Base ² = 5² - 3²
Or, Base ² = 25 - 9
Or, Base ² = 16
∴ Base = 
I.e Base = 4
Now, Cos Ф = 
So, Cos Ф = 
Now , Since
Cos ( - Ф ) = Cos Ф
So, Cos ( - Ф ) = Cos Ф = 
Hence The value of Cos (-Ф)
