A circle has a radius that is 4 centimeters long. If a central angle has a measure of 3 radians, what is the length of the arc t
hat corresponds to the angle
2 answers:
The total length of the circle is calculated by the following formula:
Lenght = 2.π.r
As r = 4c
Then,
Lenght = 2.π.4
Lenght = 8π centimetrs
Now use the rule of 3
But we have to know:
...<..> ...
Then,
8π ________ 2π <= 360°
x ________ 3π
2π . x = 8π . 3π
x = (8π . 3π) / 2π
x = (8 . 3π)/ 2
x = 12π centimenters
x ~ 37,69 c
Answer: 12 centimeters

Answer:
C = 14π cm
Step-by-step explanation:
C = πd
or
C = 2πr
Simply use the 1st equation and plug in the diameter to find you answer.
Answer:
center : (0, 2.25)
radius: 14/13
Step-by-step explanation:
x^2+(y-2.25)^2=196/169
Rewrite x^2+(y-2.25)^2=196/169
(x-0)^2+(y-2.25)^2=(14/13)^2
c=(0,2.25),r= (14/13)
