Given : perimeter of arc is 64.8cm and radius is 12.4 cm
To find : length of arc of sector
Solution:
Perimeter of an arc = radius + arc length + radius
Perimeter of arc = 64.8 cm
radius = 12.4 cm
64.8 = 12.4 + arc length + 12.4
64.8 = 24.8 + arc length
arc length = 40 cm
2) What is the length of arc of a sector, whose perimeter is 64.8cm and radius is 12.4 cm?
