Question

Find the perimeter of the figure given below:

semi circle
14 cm
​

Answer 1

Answer:

Diameter of the semi circle =14cm

Radius = 14/2 cm=7cm

Perimeter of semicircle =πr+d

Perimeter of semicircle = 22/7x7+14=22+14=36cm

The perimeter of the semicircle is 36cm.

Answer 2

Step-by-step explanation:

Perimeter of the semicircle is obtained using the formula r(π+2).

Radius r=14 cm

So, perimeter =14(π+2)..... where π = 22/7

=2(22+14)=44+28=72 cm

Hence, the answer is 72 cm.
