A farm uses an irrigation system to water crops in a circular pattern, as shown in the diagram below. The rotating arm is 100 meters in length. image c5a412e3bba44dbb9f078669b5a96961

As the arm rotates through an angle of π2 radians, it forms a circular arc. What is the length, in meters, of the arc?

A
50 meters

B
50π meters

C
200 meters

D
200π meters

could you give more information?

step-by-step explanation:

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
