The length of the arc intercepted by a central angle of 3/9 pie is 3.6 feet long. How long is the radius of the circle?
1 answer:
Answer:
B) 3.44 feet
<em>The Radius of the circle 'r' = 3.439 ≅3.44 feet</em>
Step-by-step explanation
<u><em>Step(i)</em></u>:-
<em>Given data the length of arc = 3.6 feet long</em>
l = 3.6 feet
Given central angle 'θ' =
<u><em>Step(ii)</em></u>:-
The arc length 'l' of a circle of radius 'r' with central angle 'θ' radians is given by
Arc length l = r θ
<em> </em>3.6 = r ()
put π = 3.14
now simplification, we get
<u><em>Conclusion</em></u>:-
<em>The Radius of the circle 'r' = 3.439 ≅3.44 feet</em>

To factor both numerator and denominator in this rational expression we are going to substitute 
with 
; so 
and 
. This way we can rewrite the expression as follows:
Now we have two much easier to factor expressions of the form
. For the numerator we need to find two numbers whose product is 
(30) and its sum 
(-11); those numbers are -5 and -6. 
and 
.
Similarly, for the denominator those numbers are -2 and -5.
and 
. Now we can factor both numerator and denominator:
Notice that we have
in both numerator and denominator, so we can cancel those out:
But remember than
, so lets replace that to get back to our original variable:
Last but not least, the denominator of rational expression can't be zero, so the only restriction in the variable is
