Question

12. Find the diameter of the circles having the following circumference.

(b) 62 m 8 dm (use = 3.14)​

Answer 1

Step-by-step explanation:

circumference= 62.8

2πr= 62.8

2×22/7×r= 62.8

2r= 62.8×7/22

2r= 62.8×3.14

2r=197.1992

d=197.20

Answer 2

Answer:

Let the diameter be d 

As we know that 

Circumference of the circle with diameter d is πd

Given circumference is 62.8 cm

⟹πd=62.8

⟹d=3.1462.8=20 cm

So diameter of the circle is 20 cm
