The formula to find the arc length L is
L = r*theta
where r is the radius and theta is the central angle in radians (this formula will not work if theta is in degrees)
If the central angle is 1 radian, then theta = 1 and
L = r*theta
L = r*1
L = r
So the arc length is the same as the radius
Answer: Choice A) The radius of the circle

Answer:
My age is 12 years.
Step-by-step explanation:
Given:
Sister's age = 10 years
Let my age be x.
Now according to question;
my brother's age is 1/3 of my age
So brother's age = 
Also according to question;
my sister is 6 years older than my brother;
Sister's age = 
Also given Sister's age = 10 years
hence equation to find my age will be expressed as below;

Brothers age = 
Hence my age is 12 years.
