Question

the circumstances, of two concentric rings are 88cm and 66 cm respectively. find the width between the rings (plz tell in easy process)
​

Answer 1

Answer:

width would be 3.51cm

Step-by-step explanation:

Circumference of circle 1 = 88cm

Circumference of circle 2 = 66cm

By using circumference formula 2πr we have to find radius of both circle.

c = 2πr

r = c/2π -------(eq1)

for circle 1

Putting the value of c = 88cm & π = 22/7 in eq1

we will get r = 14.01

Simillary, for circle2

we will get r = 10.5

Now,

weidth = radius of circle1 - circle2

= 14.01 - 10.5

= 3.51

Weidth of Ring is 3.51
