Question

circumference of this semi circle ??

Answer 1

Answer:

The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.

Answer 2

circumference of this semi circle = πr = 22/7 × 1.4 = 4.4 cm
