Question

find the perimeter of adjoining figure which is a semicircle including its diameter​

Answer 1

Hey Buddy !

Answer:

r(π + 2) units

Step-by-step explanation:

As we know that the perimeter of a circle = 2πr

Length of the diameter = r + r = 2r units

Perimeter of the semi circular arc = 2πr/2 = πr units.

Perimeter of a semi circle = πr + 2r = r(π + 2) units.

Hope this helps you !

Thanks !
