Answer 2

☘︎ Given :

→ Diameter of circle = 4.2 cm

☘︎ Find :

→ circumference of a circle ??

☘︎ We know that,

→ Diameter of circle = 2 × radius

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤor

→ Radius = Diameter / 2

→ So, radius = 4.2/2 = 2.1

☘︎ We know that,

→ Circumference of circle = 2πr

= 2 × 22/7 × 2.1

= 13.2

☘︎ Hence, the circumference of a circle is 13.2 cm
