Answer:
Radius=16mm
Radius=16mm
Perimeter of this figure=2r+(2.pie.r)/4
=2×16+(2×22/7×16)/4
=32+(22×16)/7×2
=32+176/7
=32+25.14
=57.14mm

Answer:
400/7 mn
Step-by-step explanation:
sector
radius= r = 16 mn
angle= x° = 90°
so it is a quadrant circle
it's length of the arc = l = 2πr/4
= 2×π×16/4
= 8π
l= 8π mm
perimeter of sector= l+2r
8π+ 2×16
8×22/7+32
= (176+224) /7
= 400/7mm
perimeter of sector= 400/7 mm
