Answer 1

Answer:

πr+πr = 2xπr 2x22/7x4=176/7cm

Answer 2

Answer:

Perimeter of the figure is (2π + 10) cm

Step-by-step explanation:

Given that, the diameter is 8 cm

As shown in the figure, the overlapping length is 3 cm.

Therefore, part of the diameter exposed at either side is (8 - 3) cm = 5 cm

Therefore, the perimeter of the figure is

[$\frac{1}{2}$.(2π.$\frac{8}{2}$) + 5] + [$\frac{1}{2}$.(2π.$\frac{8}{2}$) + 5] cm= (2π + 10) cm
