1.	The diameter of a compact disc (CD) is 12 cm. Find the circumference of the CD disc in terms of π.
Answer» ong>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"
