Question

if diameter is 3.6m then find radius and circumference of circle?
its a long question​

Answer 1

d= 3.6m

r = d/2 = 3.6/2 = 9/5m= 1.8m

Circumference of a circle = 2× pi × r

= 2×22/7×1.8

= 11.31m

Answer 2

Answer:

Radius is 1.8m

Circumference is 3.6m

Step-by-step explanation:

From property of circles:

$radius = diameter \: is \: \: 2$

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

$where \: is \: radius$

$area \: of \: circle = \pi \: r2$

Here,

Diameter of the circle is 3.6 m

Relation between radius & diameter of a circle :

= > Diameter = 2 radius

= > 3.6 m = 2 x radius

= > 1.8 m = radius

Area of the circle :

= > πr^2

= > π( 1.8 m )^2

= > 3.24 π m^2

Circumference of the circle :

= > 2πr

= > 2 x π x 1.8 m

= > 3.6 π m

*{ value of π can be taken as 3.14 or 22 / 7 or 355 / 113 }
