Answer 1

Answer:

★ Perimeter = 32cm

Step-by-step explanation:

radius = 10.5 cm , x = 60°

perimeter = length of arc + 2*radius

perimeter = (x/360°) 2πr + 2r

:- perimeter = (60°\360°) 2 x 3.14 x 10.5 + 2 x 10.5

perimeter = 32cm

Answer 2

Answer:

★ Perimeter = 32cm

Step-by-step explanation:

radius = 10.5 cm , x = 60°

perimeter = length of arc + 2*radius

perimeter = (x/360°) 2πr + 2r

:- perimeter = (60°\360°) 2 x 3.14 x 10.5 + 2 x 10.5

perimeter = 32cm
