Question

Find the diameter of a semicircle that has an arc length of of 3.

Answer 1

i know that s/2(pi)(radius) = measure of angle/360 degrees

Answer 2

But don't know how to apply this to problem.

Answer 3

Well you know that arc length= radius * the angle you consider and you have a semi circle that mean your angle will equal to 180degrees
arc length =3 and diameter =2radius apply it and you have what you need

Answer 4

But you have to convert you angle to radian not degrees

Answer 5

Thank you kindly pape for your help. I appreciate it.

Answer 6

180degrees=pie radian

Answer 7

you welcome

Answer 8

Ya, tried getting as far as I could with that advice and still not sure what to do or how to solve this.

Answer 9

okay let me solve it for you

Answer 10

arc length= radius * pie ---> 3= r*pie --> r=3/pie or diameter= 2radius

Answer 11

Thanks, I appreciate your help, pape.

Answer 12

you welcome

Answer 13

Sweet, i did it on my own and got the right answer, thanks again.
