Question

the circumference of two circles is 88 cm and the difference between the two circles is 2 cm . find the radius of the two circles

Answer 1

Answer:

= x + x +2 = 88

= 2x = 86

x = 43 , x + 2 = 45

=>2 ÷ 43 ÷ 3.14, 2 ÷ 45 ÷ 3.14

=> ~6.84, 7.16

Answer 2

Answer:

Radius = 14 cm

Step-by-step explanation:

As both the circles have same circumference it's radius is going to be same.

Formula:-

circumference of a circle = 2πr

88 = 2 × 22/7 × r

88/2 = 22/7 × r

44= 22/7 × r

44 × 7/22 = r

2 × 7 = r

14 = r
