Question

the circumference of a circle is 44cm find the radius of the circle

Answer 1

2*pi*r=circumference of circle
circumference of circle=44 cm
2*22/7*r=44
r=44*7/22*2
r=308/44
r=14 cm

Answer 2

Given, circumference = 44 cm
2πr = 44 cm

$r = \frac{44}{2\pi}$
$r = \frac{44 \times 7}{2 \times 22}$
$r = 7cm$
