Question

the diameter of two circular rings are 7 cm and 10 cm find the ratio of their circumference
pls write in detail ​

Answer 1

Answer:

7:10

Step-by-step explanation:

ASSUMPTION :

• let's assume both circles as circle A and circle B

GIVEN THAT :

• diameter of circle A = 7cm
• So, radius = 7/2cm
• diameter of circle B = 10cm
• So, radius = 10/2cm

QUESTION ASKED :

• find ratio of their circumference

SOLUTION :

According to the question,

• 2π(radius of circle A) : 2π(radius of circle B)
• 2π(7/2cm) : 2π(10/2cm)
• 7/2cm : 2π(10/2cm)/2π
• 7/2cm : 10/2cm
• 3.5cm : 5cm
• 7cm : 10cm

CONCLUSION :

So, the ratio of their circumference = 7:10
