(Lesson 11 10) on a circle with a known radius of 120mm, the length of an arc is 144MM. Find the radians of the center angle of the circle

(Lesson 11 10) on a circle with a known radius of 120mm, the length of an arc is 144MM. Find the radians of the center angle of the circle

144/120=6/5

On a circle with a known radius of 120 mm, there is a fox with a length of 144 mm. Calculate the radian and angular degree of the center angle of the arc

Arc length formula: (n * 3.14 * r) / 180
The center angle of the substituted data is 68.8 degrees and the radian is 1.2 degrees

On a circle with a known radius of 120 mm, the length of an arc is 144 mm. Find the radians of the center angle of the arc

C arc = n / 360 * π * r ² （ r*r)
360C=n*π*r ² (r*r)
n=360*c/π*r ² (r*r)
n=51840/45216(51814/14400*π）
n=180/157

There is an arc length of 144MM on a circle with a known radius of 120mm. Calculate the number of radians of the center angle of the circle:

“zgjxnf”：
(1) A circle with a radius of 120 mm and a circumference of 120 mm × two × 3.1416 = 754mm
(2) The arc length is 144 mm, accounting for 144 / 754 of the circumference
(3) The center angle is 360 ° × 144÷754=68.75°=68°45'
Answer: the circumference is 68 degrees and 45 minutes
Is that right? Good bye

On a circle with a known radius of 120mm, the length of an arc is 144MM. Calculate the radians of the center angle of the arc

Arc length L = radius R * radians x
So there are:
144 = 120 * x
The solution is x = 1.2
Therefore, the number of radians of the center angle of the arc is 1.2

The radius of the circle is 1. What is the arc length with the center angle of - 3 radians? Arc length = radian of center angle * radius of circle = 3 How is this formula derived?

Arc length C, center angle a (degrees), radius of circle R
C=2*PI*R*A/360=PI*R*A/180=R*(A*PI/180)
A * pi / 180 = (radian)
C = R * a (radian)
