The diameter of a compact disc (CD) is 12 cm. Find the circumference of the CD disc in terms of π.​

Answer 1

Answer:

${ \bold{ \red{Given}}}$

• Diameter of compact disc =12 CM

${ \bold{ \green{ Find}}}$

• circumference of the CD disc in terms of π.

${ \bold{ \orange{Solution}}}$

⟶ Diameter of disc = 12cm

We know that Radius is half of diameter.

⟶ Radius = 12/2= 6

Radius of compact disc is 6cm

${ \boxed{ \bold{circumference \: \: of \: \: circle =2πr }}}$

⟶2×π×6

⟶12π

"Circumference of the CD disc is 12π"

Answer 2

Answer:

24πcm
