A circular disc of diameter 7 cm is divided in two equal parts find the perimeter of each semicircular shape disc (use π=22/7
Answers
radius of the circulae disc = 7/2 cm = 3.5 cm
circumference of the circular disc = 2πr
= 2*22/7*3.5
= 22 cm
the perimeter of each semi circular shaped disc
= (circumference of the circular disc/2)
+ (diameter of circle)
= (22/2) + (7)
= 18 cm
the perimeter of each curcular shaped disc is 18 cm.
Answer:

= 18 cm
the perimeter of each curcular shaped disc is 18 cm.
