length of a sector

LENGTH OF A SECTORRRRRR

(we’re jus gonna say that * is theta okay, like the little weird O symbol ya know?)

*/360

length = fraction of circle x circumference

*/360 x C = length

72/360

length = fraction x circum

72/360 × 85 = 17

back of book one physical notes same as these

the 30% test also had questions on it
