Answer:
90.27mm
Explanation:
radius=16mm
diameter=16mm x 2
=32mm
total length=1/2 x pi x 32mm +20mm+20mm
= 90.27mm (nearest hundredth)
90.27 mm (nearest hundredth)
Circumference of a circle = (where r is the radius)
Therefore, the arc length = 1/2 x 2 x x 16 = 16
So total perimeter = 2 x 20 + 16 = 90.27 mm (nearest hundredth)
