Radius of the circle = 7 cm
» Circumference of semicircle = 2πr/2 = πr
= 22/7 × 7
= 22 cm
» Circumference of circle = 2πr = 2×22/7×7
= 44 cm
» Circumference of semicircle = 2πr/2 = πr
= 22/7 × 7
= 22 cm
» Circumference of circle = 2πr = 2×22/7×7
= 44 cm

Perimeter of the semicircle is 22 cm.
- Radius of a circle is given as 7 cm.
- We have to find perimeter of the semicircle ,
- Circumference of the circle is given as 2πr.
- Circumference of the semicircle = πr.
- Now we substitute the value of the radius and evaluate the perimeter.
- Perimeter of semicircle = (22/7)×7 = 22 cm.
