Question

Find the circumference off a semicircular shape on a line of length 14 cm​

Answer 1

Answer:

let length be d.

r =½d

r=7

circumference of semicircle = πr

= 22/7 ×7

= 22 cm

Answer 2

Answer:

Step-by-step explanation:

circumference of circle = 2πr

circumference of semicircle = 2πr/2

                                              = πr

And as in semicircle there is also a diameter below the figure so the final formula will be πr+d

Diameter = 14 cm

Radius = 7 cm

= π * 14 + 7

= 14π+7 cm

The answer is 14π+7 .
