Question

find the circumference of circle whose radius is 30 cm​

Answer 1

Answer:

188.57cm

Step-by-step explanation:

$2\pi {x}$

x = radius

2 × 22/7 × 30= 188.57 cm

Answer 2

Answer:

Circumference = 188.4 cm

Step-by-step explanation:

Radius = 30 cm

Circumference of the circle = 2πr

( when the radius is given) = 2 × 3.14 × 30

= 6.28 × 30

= 188.4
