Question

The circumference of a circle is 37.68 centimetres. What is the circle's radius? Use 3.14 for ​pi

Answer 1

Answer:

let the radius be r

we know,

1/2*pi*r=37.68

3.14r=37.68*2

r=37.68*2/3.14

r=24

Answer 2

GIVEN :–

• Circumference of circle = 37.68 cm

TO FIND :–

• Radius of circle = ?

DIAGRAM :–

$\setlength{\unitlength}{20}\begin{picture}(6, 6) \put(1,1 ){\circle{14}} \put(1,1 ){\circle*{0.15}}\put(1, 1){\line(1,0 ){1}}\put(1.25,1.25 ){ \sf r }\put(2.5,1.5 ){ \sf circumference \: of \: the \: circle }\put(2.5, 1){ \sf = 37.68 \: cm }\put(3,0 ){ \boxed{ \bf @AK14380 }}\end{picture}$

SOLUTION :–

• We know that –

$\\ \dashrightarrow \large{\boxed { \bold{Circumference\:\:of\:\:circle= 2\pi r}}}$

• Put the values –

$\\ \implies { \bold{37.68= 2\pi r}}$

$\\ \implies { \bold{37.68= 2(3.14)r}}$

$\\ \implies { \bold{37.68= 6.28r}}$

$\\ \implies { \bold{r = \cancel \dfrac{37.68}{ 6.28}}}$

$\\ \implies { \bold{r =6}}$

• Hence –

$\\ \implies \large { \boxed{ \bold{Radius =6 \: cm}}}$
