Question

Find the circumference of circle whose diameter is 5.6 cm.(Note : take =22/7)

Answer 1

Heya!!!

HERE IS THE ANSWER

Given Diameter =5.6 cm

So its radius= (5.6/2)cm

=2.8 cm

Now As we know circumference of a circle

$2 \: \pi \: r \\ = 2 \times \frac{22}{7} \times 2.8 \\ = 2 \times 22 \times 0.4 \\ = 17.6 \: cm$
Hope it helps you.

Answer 2

Hi there,

Given,

Diameter = 5.6 cm

hence,radius = 5.6/2 = 2.8 cm

As we know,

Circumference of the Circle = 2$\pi r$

=2×22/7×2.8

=44×0.4 = 17.6 cm

Thank you
