Question

find the perimeter of a semicircle of base 14m

Answer 1

Answer:

Step-by-step explanation:

Perimeter= circumference of semicircle

Circumference of semicircle= 2πr/2

=πr

=( 22/ 7)×7

=22 meters

Answer 2

Answer: 36 m

Step-by-step explanation:

2r = d r = 14/2 = 7

Lets consider a full circle

circumfrance of a circle = 2πr

= 2 x 22/7 x 7

= 2 x 22

= 44 m

half circumfrance is needed

1/2 x 44 = 22m

But here the diameter is also included in perimeter

22 + 14 = 36m
