Question

13) Find the diameter of a circular drum
which has a circumference of 2.2 m.

please give solution step by step.





please tell the answer.​

Answer 1

Answer:

7m

Step-by-step explanation:

We know that Circumference of circle = 2Πr

Therefore 2.2 = 2Πr

r = 2.2 × 7/44

r = 7.7/22

r = 77/220 = 7/20

Therefore diameter = 2r

Diameter = 2 × 7/20 = 7/10 = 0.7 m And

I hope you understand it.

Thanks

Answer 2

22/7×d=2.2m

d=2.2×7/22m

d=7/10m

d=0.7m

your answer is 0.7m
