Question

Find the radius of a circle whose circumference is 36 cm of Class 5

Answer 1

Circumference of circle is 2piR
Where R is radius and pi is 22/7 or 3.14
Putting the value of circumference and radius
We have 36=2*22*R/7
36*7/22*2=R
R=63/11cm

Answer 2

$\LARGE\underline{\underline{\sf \red{Given}:}}$

• Circumference of circle = 36cm

$\large\underline{\underline{\sf \red{To\:Find}:}}$

• Radius of circle (r) = ?

$\LARGE\underline{\underline{\sf \red{Solution}:}}$

We know that :

$\large{\boxed{\sf Circumference\:of\:Circle=2πr }}$

$\implies{\tt 36=2×\dfrac{22}{7}×r }$

$\implies{\tt r=\dfrac{36×7}{2×22}}$

$\implies{\tt r=\dfrac{252}{44}}$

$\implies{\tt r=5.72cm }$

$\LARGE\underline{\underline{\sf \red{Answer}:}}$

•°• Radius of circle is 5.72cm
