00:01 The circle has a radius of nine inches.
00:11 The central angle is 60 degrees.
00:19 We want to find area of the sector.
00:25 The formula for area of the sector is 1 half r squared theta.
00:32 The theta must be in radiant measure.
00:37 So the first thing we're going to do is convert that angle 60 degrees, to radians by multiplying by pi over 180...
