Question

find the sector with given measures find the length of the arc area and perimeter central angle =120 r=12​

Answer 1

Answer:

For The Sectors With Given Measures,Find The Length Of The Arc,Area And Perimeter. 1. Central Angle 120 Degree,D=12.6 Cm Answer

Answer:

Step-by-step explanation:

= 6.6 cm.

Area = (120/360)π R² =(1/3) (22/7) (6.3)² = 41.58 cm²

Perimeter = 6.6 + 10.9 = 17.5 cm.

Answer 2

Answer:

Step-by-step explanation:

Area (120 /360)πr^2 = (1/3 ) (22/7) (12^2)

= (1/3) (22/7) (144) = 150.58 cm

Perimeter = 6.6+10.9 =17.5 cm
