Answer 1

Answer: PLEASE BRAINLIEST MY ANSWER

∴ length of arc of circle = 1.4cm

Step-by-step explanation:

Q) Find the length of arc of a circle with radius 0.7cm and area of sector is 0.49cm^2​

⇒ given, radius of circle = 0.7cm

area(sector of circle) = 0.49cm^2

length of arc of circle = ?

area(sector of circle) = [(length of arc of circle) × (radius of circle)] / 2

∴        0.49              =     ( L × 0.7) / 2

∴ (0.49 × 2) / 0.7     =       L

∴          L                  =   (0.49 × 2) / 0.7

∴          L                  =        0.7 × 2

∴          L                  =         1.4cm

∴ length of arc of circle = 1.4cm
