Question

perimeter of the sector of circle with radius 5.7m is 27.2m .Find the length of arc of sector.​

Answer 1

Answer:

length of arc of sector is 15 .8 m

Step-by-step explanation:

Radius of the sector r = 5.7 m

Perimeter of the sector P = 27.2 m

Perimeter of the sector is

27.2= Radius + length of arc+ radius

27.2= 2*Radius + arc length of sector

27.2= 2* 5.7+ arc length of sector

arc length of sector= 27.2-11.4

arc length of sector = 15.8 m

Answer 2

Answer:

Hence, the Area of sector= 45.03 cm².
