Question

a 3 m wide road runs around a circular park whose circumference is ​

Answer 1

$radius = 3m\\\\circumference \ of \ circle = 2\pi r\\\\= > 2*22/7 * 3 = 6 * 22/7 = 18.85 \ m \\\\hope \ it \ helps \ !!$

Answer 2

AnSwEr -:


18.85 is the circumference of a circle ⭕️.


_____________________________

Circumference of circle ⭕️ -:

C=2πr

C = circumference

R= radius

π = 22/7 or 3.14

_____________________________

Given ,

Radius or widnes of road = 3 m

To find ,

Formula for finding the circumference of

circle -:

C=2πr

2 x 22/7 x 3

44/7 x 3

6.28 x 3

= 18.85 m

18.85 m is the circumference of circle

⭕️ .

______________________________


Formula used in circle-:

Diameter of a Circle D = 2 × r

Circumference of a Circle C = 2 × π × r

Area of a Circle A = π × r^2

Here ,


D= diameter

R= Radius

C= circumference

A= area

π = 22/7 or 3.14
