Question

If you walk around the edge of a circle of 120 metre diameter,then how far would you walk?

Answer 1

Answer:

i walked 37.71 meters(approx)

Answer 2

Step-by-step explanation:

$\huge\bf\underline\blue{answer}$

given,

diameter of circle = 120m

to find,

how far would we walk?

$\huge\sf\underline{let's\: understand}$

to find how far that we walk is simply to find the perimeter of the circle i.e circumference of the circle .

so, why we need to find only the circumference of the circle?

as they said that we are walking around the edge of the circle i.e nothing but we are walking around the circle.

that is the reason we need to find the circumference of the circle.

required formula:-

$radius \: of \: the \: circle \: = \frac{diameter \: of \: the \: circle}{2}$

$circumference \: of \: the \: circle \: = 2 \times \pi \times r$

$\huge\fcolorbox{black}{pink}{✓solution✓}$

.: diameter of the circle (d) = 120m

radius of the circle = 120m/2 = 60m

.: radius of the circle = 60m.

.: circumference of the circle= 2×3.14×60m

= 6.28 × 60m

= 376.8m

.: $\huge\bf\underline\green{.:\: circumference \: of \: the \: circle\: =\: 376.8m}$
