Question

what is the circumference of a diameter of 5.6 m​

Answer 1

$radius = \frac{5.6}{2} = > 2.8 \: m$

$circumference = > 2\pi \: r \\ = > 2 \times \frac{22}{7} \times 2.8 \\ = > 17.6 \: m$

Answer 2

Answer:

Circumference = 17.6 m

Step-by-step explanation:

D = 5.6m

So, R = 5.6/2 = 2.8m

Now,

Circumference = 2 pie R

= 2x22/7x2.8

= 2x22x0.4 (because, 2.8 and 7 gets cancelled)

= 44x0.4

= 17.6m
