Step-by-step explanation:
object. circumference diameter. c/d
1.bangle. 48.4cm 15.4cm 3.142
2.lid of a zar. 44cm 14cm 3.142
3.A metal cup 8.8cm 2.8 cm 3.142
result :- c/d always equal to π or 22/7 or 3.14
Answer:
Step-by-step explanation:
let us consider radius of a bangle is 2.5 cm
then circumference = 15.71 cm
diameter = 5cm
ratio C/D = 15.71/5
= 3.14/ 1
= 3:1 ( approx)
let us consider radius of a jar = 5 cm
then circumference = 31.42 cm
diameter =10 cm
ratio = 31.42 /10
= 3.142/1
= 3:1 ( approx)
let us consider the metal cup radius 1.5 cm
then circum erence = 9.42 cm
diamater = 3cm
ratio = 9.42/3
=3.14/1
=3:1 (approx)
note = the circumference of a circle is 3.14 times i.e. Pi times the diameter of the circle
