Question

Find the diameter and radius of the circle whose circumference is 1/7 cm ( use 22/7 instead of 3.14)

Answer 1

Answer:

Radius is 0.23 cm and diameter is 0.46 cm

Step-by-step explanation:

We no that,

Circum of circle,

c=2πr

1/7=2×22/7×r

(1×7)/(2×22×7)=r

1/44=r

r=0.23 cm

Therefore, d =2r

d=2×0.23

d=0.46 cm
