Question

2. Find the perimeter of a semi circle who's diameter is 14cm
​

Answer 1

Answer:

36cm

Step-by-step explanation:

Radius = 7cm

Perimeter of semi-circle = πr + 2r

= 22/7 * 7 + 2 * 7

= 22 + 14

= 36cm

Answer 2

Answer:

Sol.:- Given,

Diameter=14cm.

So,

Radius=D/2

=14/2

=7cm

Now,

Perimeter=2πr

=2×22/7×7

=2×22

=44cm.

Hence, the perimeter of Circle=44cm.
