Answer 1

(I hope you meant circumference)

Question:

The circumference of two circles are 44 cm and 110 cm respectively. Find the difference between their radii.

Answer:

- 10.5

Method:

Circumference of a circle = 2πr

Circumference of first circle:

2πr = 44

2 × 22/7 × r = 44

22/7 × r = 44/2

= 22

r = 22 × 7/22

= 7

Circumference of second circle:

2πr = 110

2 × 22/7 × r = 110

22/7 × r = 110/2

= 55

r = 55 × 7/22

= 17.5

The radii of the two circles are 7 and 17.5 respectively.

Difference between the two radii = 7 - 17.5

= - 10.5
