Question

6 Sudhanshu divides a circular disc of radius 7 cm in two equal parts.
What is the perimeter of each semicircular shape dise? (Uses =
22/7)​

Answer 1

Answer:

Solution. Given that radius (r) = 7 cm. Thus, perimeter of each semicircular disc = 22 cm + 14 cm = 36 cm.

Step-by-step explanation:

this is your answer

Answer 2

Perimeter of each semicircle = 2πr/2 + diameter (as semicircle is half of a circle and has an extra diameter which will be considered in the perimeter)

= πr + 2r

= r(π+2)

= 7(22/7 +2)

= 7 (29/7)

= 29 cm

Therefore, perimeter of each semicircle is 29cm
