Radians and Circles by Stephen Blatch https://padlet.com/shb4/goxk1xfgltyl A radian is the angle subtended at the centre of a circle by an arc equal in length to the radius. en-us 2016-11-22 11:48:50 UTC 2016-11-23 14:41:09 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Pizza.png Task: shb4 https://padlet.com/shb4/goxk1xfgltyl/wish/139317605 1. Using the above definition find:
  1. How many radians are there in a circle?
  2. How do you convert between degrees and radians?
  3. How do you convert between degrees and radians?
2. How can this be used to find:
  1. The length of and arc?
  2. The area of a sector?
