Question

Find the perimeter of a semi circle with the radius of 22m.​

Answer 1

Answer:

22× 36/7

Step-by-step explanation:

perimeter of circle is 2πr

so perimeter of of semicircle = πr + 2r

perimeter of semicircle = r (π +2)

perimeter of semicircle = 22 (22/7 + 2)

perimeter of semicircle = 22 × 36/7

Answer 2

Answer: 113.14m or 36π

Step-by-step explanation:

Radius : 22

Circumference of Semi-Circle = πr + 2r

= 22 × 22 + 2 × 22

_____

7

= 69.14 +44

= 113.14m or 36π

Therefore Perimeter of Semi-Circle is 113.14m.
