Question

If diameter is 6cm then find her Radius and circumference.
​

Answer 1

Answer:

radius is 3 cm

circumference is 2πr

=2x 22/ 7 x 3= 132/7

hiii how are u can we be friends

Answer 2

$\frak {\large{Given}}$

$\rm{ \hookrightarrow diameter = 6cm}$

$\frak{ \large{Formula \: to \: be \: used}}$

$\rm{ \hookrightarrow diameter = 2 \times radius}$

$\rm{ \hookrightarrow circumference = 2\pi r}$

$\frak{ \large{Solution}}$

$\sf \purple{ \longmapsto Radius = \frac{diameter}{2} = \frac{6}{2} = 3 }$

$\sf{ \mapsto Circumference = 2\pi r= 2 \times \frac{22}{7} \times 3}$

$\sf \green{ \longmapsto Circumference = 18.85cm}$
