Find the perimeter of this sector. give your answer in terms of

Perimeter = 24 +  8π /3 m.

Step-by-step explanation:

Arc length = rC  where r = radius and C = angle in radians.

40 degrees = 40 π / 180

= 2π /9 radians.

Arc length = 12 * 2π /9

= 8π /3 m.

Perimeter of the sector = 2*12 + 8π /3

= 24 +  8π /3 m.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
